• System restore with no mouse or keyboard.

  - by user62371

  I accidentally installed some USB drivers to my Windows 7 system, they were the wrong ones and now my keyboard and mouse won't work. A system restore would get rid of them, but obviously I can't control my computer to make that happen. Keyboard and mouse still work before windows has loaded, in the BIOS and boot system, so can I do anything from there? I've already tried booting into another OS, accessing my windows filesystem and deleting the Program Files entry, but it didnt work so they must go deeper than that. Or could i launch it from a remote machine? I've got some VNC server insalled so if i could get that running that could work.

• Keyboard and mouse stop working

  - by senzen

  I have computer. I used it for 6 month without having problem. But now i have problem on keyboard and mouse. Every time turn on the computer it work correctly for 2 or 3 minutes. After that it stop responding. First I thought it have problem with OS. Then I installed windows. But now also it happen as before. When it happen I change the port that mouse and keyboard are connected. Then it again work for 2 or 3 minutes and stop working. I check whether the port I used before can used for other devices so I insert USB flash drive. It detected. So I am confuse what the real problem is. I hope will get your help soon. Thanks.

• why is my Bamboo pen always drawing and a yellow note pad appears?

  - by cboi

  I have had a Bamboo pen and touch tablet for a couple years but have not used it in a long time. Now that I'm trying to use it again it is behaving very strangely. It won't drag anything on my desktop, the minute I try there is this yellow pad that appears and the pen draws a line on it instead of dragging the file. The yellow pad and drawn line disappear the second I lift the pen from the tablet. The most frustrating is it does the same thing when I try to draw in Photoshop. It won't draw with the paintbrush on my canvas because the minute I try to this yellow pad appears and it draws a line on it instead of on the canvas, which disappears the second I lift the pen from the tablet. It also bizarrely automatically switches from the paintbrush to the automatic selection tool. Has anyone had this problem? Any suggestions on how to fix this? I operate with Mac OS X 10.5.8

• Why has my zoom feature stopped working in OSX 10.6?

  - by Kev

  For the life of me I can't get the zoom feature to work on OSX 10.6 on my Max Mini. It's a fresh install, I have the wireless mighty mouse with the small grey scroll ball and the small wireless Apple metal keyboard. I've tried enabling "Zoom using scroll ball whilst holding ^Control" mouse System Preference. I also tried enabling Zoom in "Universal Access" in the System Preferences. This did work in OSX 10.5, but seems to have stopped since I installed 10.6.

• Cannot find Power Management Tab in XP

  - by Andrew Heath

  I have the problem that when I send my computer to sleep it wakes if you bump the table, floor, burp etc. I have read many threads that say go to Device Manager Mouse Properties Power Management Tab and uncheck the box for wake. My problem is I do not have a Power Management Tab! Anyone know how to enable the tab or stop the mouse from waking my machine? And no, turning it upside down doesn't work either!

• Ubuntu 10.04 not detecting multiple monitors

  - by user28837

  I have 2 graphics cards, the output from the lspci: 01:00.0 VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4850] 02:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4350] I have one monitor connected to the 4850 and 2 connected to the 4350. However when I go into System Preferences Monitors the only monitor shown is the one connected to the 4850. Is there something I need to enable for it to be able to use the other card? How do I get this to work. Thanks.

• How do I drag my widgets without dragging other widgets?

  - by Cypher

  I have a bunch of drag-able widgets on screen. When I am dragging one of the widgets around, if I drag the mouse over another widget, that widget then gets "snagged" and is also dragged around. While this is kind of a neat thing and I can think of a few game ideas based on that alone, that was not intended. :-P Background Info I have a Widget class that is the basis for my user interface controls. It has a bunch of properties that define it's size, position, image information, etc. It also defines some events, OnMouseOver, OnMouseOut, OnMouseClick, etc. All of the event handler functions are virtual, so that child objects can override them and make use of their implementation without duplicating code. Widgets are not aware of each other. They cannot tell each other, "Hey, I'm dragging so bugger off!" Source Code Here's where the widget gets updated (every frame): public virtual void Update( MouseComponent mouse, KeyboardComponent keyboard ) { // update position if the widget is being dragged if ( this.IsDragging ) { this.Left -= (int)( mouse.LastPosition.X - mouse.Position.X ); this.Top -= (int)( mouse.LastPosition.Y - mouse.Position.Y ); } ... // define and throw other events if ( !this.WasMouseOver && this.IsMouseOver && mouse.IsButtonDown( MouseButton.Left ) ) { this.IsMouseDown = true; this.MouseDown( mouse, new EventArgs() ); } ... // define and throw other events } And here's the OnMouseDown event where the IsDraggable property gets set: public virtual void OnMouseDown( object sender, EventArgs args ) { if ( this.IsDraggable ) { this.IsDragging = true; } } Problem Looking at the source code, it's obvious why this is happening. The OnMouseDown event gets fired whenever the mouse is hovered over the Widget and when the left mouse button is "down" (but not necessarily in that order!). That means that even if I hold the mouse down somewhere else on screen, and simply move it over anything that IsDraggable, it will "hook" onto the mouse and go for a ride. So, now that it's obvious that I'm Doing It Wrong™, how do I do this correctly?

• Using Bullet physics engine to find the moment of object contact before penetration

  - by MooMoo

  I would like to use Bullet Physics engine to simulate the objects in 3D world. One of the objects in the world will move using the position from 3D mouse control. I will call it "Mouse Object" and any object in the world as "Object A" I define the time before "mouse object" and "Object A" collide as t-1 The time "mouse object" penetrate "Object A" as t Now there is a problem about rendering the scene because when I move the mouse very fast, "Mouse object" will reside in "Object A" before "Object A" start to move. I would like the "Mouse Object" to stop right away attach to the "Object A". Also If the "Object A" move, the "Mouse object" should move following (attach) the "Object A" without stop at the first collision take place. This is what i did I find the position of the "Mouse Object" at time t-1 and time t. I will name it as pos(t-1) and pos(t) The contact time will be sometime between t-1 to t, which the time of contact I name it as t_contact, therefore the contact position (without penetration) between "Mouse object" and "Object A" will be pos(t_contact) then I create multiple "Mouse object"s using this equation pos[n] = pos(t-1) * C * ( pos(t) - pos(t-1) ) where 0 <= C <= 1 if I choose C = 0.1, 0.2, 0.3,0.4..... 1.0, I will get pos[n] for 10 values Then I test collision for all of these 10 "Mouse Objects" and choose the one that seperate between "no collision" and "collision". I feel this method is super non-efficient. I am not sure the way other people find the time-of-contact or the position-of-contact when "Object A" can move.

• Custom NSView in NSMenuItem not receiving mouse events

  - by Dennis

  I have an NSMenu popping out of an NSStatusItem using popUpStatusItemMenu. These NSMenuItems show a bunch of different links, and each one is connected with setAction: to the openLink: method of a target. This arrangement has been working fine for a long time. The user chooses a link from the menu and the openLink: method then deals with it. Unfortunately, I recently decided to experiment with using NSMenuItem's setView: method to provide a nicer/slicker interface. Basically, I just stopped setting the title, created the NSMenuItem, and then used setView: to display a custom view. This works perfectly, the menu items look great and my custom view is displayed. However, when the user chooses a menu item and releases the mouse, the action no longer works (i.e., openLink: isn't called). If I just simply comment out the setView: call, then the actions work again (of course, the menu items are blank, but the action is executed properly). My first question, then, is why setting a view breaks the NSMenuItem's action. No problem, I thought, I'll fix it by detecting the mouseUp event in my custom view and calling my action method from there. I added this method to my custom view: - (void)mouseUp:(NSEvent *)theEvent { NSLog(@"in mouseUp"); } No dice! This method is never called. I can set tracking rects and receive mouseEntered: events, though. I put a few tests in my mouseEntered routine, as follows: if ([[self window] ignoresMouseEvents]) { NSLog(@"ignoring mouse events"); } else { NSLog(@"not ignoring mouse events"); } if ([[self window] canBecomeKeyWindow]) { dNSLog((@"canBecomeKeyWindow")); } else { NSLog(@"not canBecomeKeyWindow"); } if ([[self window] isKeyWindow]) { dNSLog((@"isKeyWindow")); } else { NSLog(@"not isKeyWindow"); } And got the following responses: not ignoring mouse events canBecomeKeyWindow not isKeyWindow Is this the problem? "not isKeyWindow"? Presumably this isn't good because Apple's docs say "If the user clicks a view that isn’t in the key window, by default the window is brought forward and made key, but the mouse event is not dispatched." But there must be a way do detect these events. HOW? Adding: [[self window] makeKeyWindow]; has no effect, despite the fact that canBecomeKeyWindow is YES.

• XNA - Mouse coordinates to word space transformation

  - by Gabriel Butcher

  I have a pretty annoying problem. I would like to create a drawing program, using winform + XNA combo. The most important part would be to transform the mouse position into the XNA drawn grid - I was able to make it for the translations, but it only work if I don't zoom in - when I do, the coordinates simply went horrible wrong. And I have no idea what I doing wrong. I tried to transform with scaling matrix, transform with inverse scaling matrix, multiplying with zoom, but none seems to work. In the beginning (with zoom value = 1) the grid starts from (0,0,0) going to (Width, Height, 0). I was able to get coordinates based on this grid as long as the zoom value didn't changed at all. I using a custom shader, with orthographic projection matrix, identity view matrix, and the transformed world matrix. Here is the two main method: internal void Update(RenderData data) { KeyboardState keyS = Keyboard.GetState(); MouseState mouS = Mouse.GetState(); if (ButtonState.Pressed == mouS.RightButton) { camTarget.X -= (float)(mouS.X - oldMstate.X) / 2; camTarget.Y += (float)(mouS.Y - oldMstate.Y) / 2; } if (ButtonState.Pressed == mouS.MiddleButton || keyS.IsKeyDown(Keys.Space)) { zVal += (float)(mouS.Y - oldMstate.Y) / 10; zoom = (float)Math.Pow(2, zVal); } oldKState = keyS; oldMstate = mouS; world = Matrix.CreateTranslation(new Vector3(-camTarget.X, -camTarget.Y, 0)) * Matrix.CreateScale(zoom / 2); } internal PointF MousePos { get { Vector2 mousePos = new Vector2(Mouse.GetState().X, Mouse.GetState().Y); Matrix trans = Matrix.CreateTranslation(new Vector3(camTarget.X - (Width / 2), -camTarget.Y + (Height / 2), 0)); mousePos = Vector2.Transform(mousePos, trans); return new PointF(mousePos.X, mousePos.Y); } } The second method should return the coordinates of the mouse cursor based on the grid (where the (0,0) point of the grid is the top-left corner.). But is just don't work. I deleted the zoom transformation from the matrix trans, as I didnt was able to get any useful result (most of the time, the coordinates was horrible wrong, mostly many thousand when the grid's size is 500x500). Any idea, or suggestion? I trying to solve this simple problem for two days now :\

• Don't let the mouse wake up displays from standby

  - by progo

  I like to put my displays to powersave/standby mode when I leave the computer for a while. It would be ok if it weren't for oversensitive mouse. Sometimes the driver reads in some movement that's not visible to the naked eye (the cursor, that is) and it breaks the power save. It would wait for another 10 minutes before going back to its standby. My workaround is the following script bound to C-S-q: xlock -startCmd 'xset dpms 2 2 2' -endCmd 'xset dpms 600 1200 1300' -mode blank -echokeys -timeelapsed +usefirst By using xset I set the values to 2 seconds each before going to standby. It's not nice, anyway. Sometimes there are cool fortunes that I want to read before typing in the password. I could keep the cursor moving but it's cludgy. (By the way, xlock's option mousemotion doesn't help -- it just hides the cursor but the displays fire up nevertheless.) So the question: is there a way to make displays go standby and stay there until a keyboard key is pressed? I'm running gentoo and recent Xorg, but I hope the answer doesn't have to be distro-specific. Basically the answer can be as simple as how to enable/disable mouse within command line? It think that would do the job if DPMS doesn't know the idea.

• Ubuntu 10.04 Keyboard and Mouse Freezing Problem

  - by nitbuntu

  I had a partition setup with Windows XP and Ubuntu 8.04 dual booting. I recently upgraded to Ubuntu 10.04 by installing fresh from CD but leaving the previous /home folder as is. Things seemed to be working fine, but started finding that my mouse and keyboard were freezing. After a quick search on the internet, I found the following suggestions as shown here:- Ubuntu Forums Here the suggestion was to:- Edit /etc/default/grub, go to the line that begins like: GRUB_CMDLINE_LINUX_DEFAULT= Change it to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off" After that, run this command: sudo update-grub and Reboot This seemed to have resolved the issue but after a couple of days I again find my mouse and keyboard freezing. I also find that my parallel port printer had also stopped working. I have saved the output of dmesg and my syslog. The first can be viewed here but the syslog had too many characters, so if someone can suggest an alternative to freetexthost, I can post it there. Moreover, if there is any other information that should be provided, do let me know. I do hope we can get to the bottom of this issue. Thank you in advance for any help that could be provided.

• Dell D630 - Touchpad does not move the mouse cursor

  - by Dean McKenzie

  Windows XP - Dell D630 - Synaptics Touch Pad driver installed. The system tray icon that shows the movement of your finger on the touchpad registeres movement. The scroll feature of the touchpad works on any window with a scroll bar. The double click works even. But it never actually moves the cursor on the screen. An external mouse works with out problems, and I've replaced the palm-rest/touchpad and it continues to happen. The touch stick in the middle of the keyboard works without problems. Does anyone have any ideas?

• How do I use key combinations on an axis on a joystick in xorg?

  - by valadil

  I'm using xserver-xorg-input-joystick on Debian Stable so I can use a joystick in place of the mouse. I have mouse movement working correctly, but got stuck trying to add functions for some other keys. These work: #Left stick #Pointer Option "MapAxis1" "mode=relative axis=1.5x" Option "MapAxis2" "mode=relative axis=1.5y" #Right stick #Arrow keys Option "MapAxis4" "mode=relative keylow=Left keyhigh=Right" Option "MapAxis5" "mode=relative keylow=Up keyhigh=Down" But when I try to make key combos (so I can navigate windows and screens in xmonad) I have no luck. #dpad #xmonad focus #up/down toggle window. l/r choose screen. Option "MapAxis8" "mode=relative keylow=Super_L,k keyhigh=Super_L,j" Option "MapAxis7" "mode=relative keylow=Super_L,w keyhigh=Super_L,e" I've also tried Super_R, plain old Super, Meta, and mod4mask, and anything else I can think of. These buttons print the letter, but don't appear to hold down the modifying key. The exception to that is shift. If I specify Shift_L or Shift_R, I get a capital letter. xev indicates that modifier keys are being pressed. If I lower Axis8, I get press Super_L, press k, release k, release Super_L. That looks like it should be working. Maybe this is an xmonad problem and not a joystick driver one? I'm also having trouble with getting an axis to use other XF86 keys: # triggers # song selection Option "MapAxis3" "mode=relative keylow=none keyhigh=XF86AudioForward" Option "MapAxis6" "mode=relative keylow=none keyhigh=XF86AudioBack" That does nothing. Any idea why? If it turns out that this isn't something I can do on an axis, but would work with a button, is there a way to treat my joysticks as buttons? Also, if anyone has suggestions for the other 5 buttons I'll have left after mouse buttons are bound, I'm listening.

• USB question (how durable is it, how should I workaround this)

  - by Shiki

  The plot is quite simple. Got a Razer mouse. If I plug it in, it works. After a shutdown/hibernation, I have to replug it entirely at the back of the PC. (It works in my laptop even after severel shutdown, etc, so yes I guess it's my motherboard.. but it still got 2 years of warranty and it comes with quad SLI, its not an old motherboard at all. (MSI P7N SLI FI (bought it after a hungarian guy's recommendation)). So. I only could come up with one "solution". Get 3 USB cable (you know, USB-USB). If its possible the shortest ones (don't know if the responsibility/anything will worsen), AND replug only the middle+closest to the USB port junction, since those are replaceable. What do you think? Any other idea? (BIOS is updated, mouse driver ... doesn't really matter, the mouse won't even blink a bit after this happens. It lights up and goes totally dead.)

• Linux Firefox copy/paste issue

  - by Daniel

  I'm using Firefox 15.0.1 on Fedora 17 without running gnome or kde. The problem I'm having is that whenever I select text outside of Firefox, for instance in xterm, the middle mouse button doesn't copy it inside Firefox, for instance in a text area, but rather brings up a context menu. A related problem is that whenever I middle click inside Firefox, for instance in a text input, the middle mouse button brings up a menu when I'd like it to paste. Even if I select Paste in the menu not the selected text (from outside Firefox) gets pasted but the last selected text inside Firefox. In about:config I tried "middlemouse.paste true" and also "middlemouse.paste false" together with the add-on Auto Copy but no combination worked. A middle mouse click always brings up a context menu. But the Auto Copy did help with automatically copying selected text to the clipboard. With Auto Copy the only problem I still have is pasting by middle button. Follow up: somehow the problem solved itself. After removing Auto Copy firefox works as I expect it to (as any X application). I can't figure out why it was not doing it before, probably I was messing too much with about:config and not restarting frequently enough.

• Ball bouncing at a certain angle and efficiency computations

  - by X Y

  I would like to make a pong game with a small twist (for now). Every time the ball bounces off one of the paddles i want it to be under a certain angle (between a min and a max). I simply can't wrap my head around how to actually do it (i have some thoughts and such but i simply cannot implement them properly - i feel i'm overcomplicating things). Here's an image with a small explanation . One other problem would be that the conditions for bouncing have to be different for every edge. For example, in the picture, on the two small horizontal edges i do not want a perfectly vertical bounce when in the middle of the edge but rather a constant angle (pi/4 maybe) in either direction depending on the collision point (before the middle of the edge, or after). All of my collisions are done with the Separating Axes Theorem (and seem to work fine). I'm looking for something efficient because i want to add a lot of things later on (maybe polygons with many edges and such). So i need to keep to a minimum the amount of checking done every frame. The collision algorithm begins testing whenever the bounding boxes of the paddle and the ball intersect. Is there something better to test for possible collisions every frame? (more efficient in the long run,with many more objects etc, not necessarily easy to code). I'm going to post the code for my game: Paddle Class public class Paddle : Microsoft.Xna.Framework.DrawableGameComponent { #region Private Members private SpriteBatch spriteBatch; private ContentManager contentManager; private bool keybEnabled; private bool isLeftPaddle; private Texture2D paddleSprite; private Vector2 paddlePosition; private float paddleSpeedY; private Vector2 paddleScale = new Vector2(1f, 1f); private const float DEFAULT_Y_SPEED = 150; private Vector2[] Normals2Edges; private Vector2[] Vertices = new Vector2[4]; private List<Vector2> lst = new List<Vector2>(); private Vector2 Edge; #endregion #region Properties public float Speed { get {return paddleSpeedY; } set { paddleSpeedY = value; } } public Vector2[] Normal2EdgesVector { get { NormalsToEdges(this.isLeftPaddle); return Normals2Edges; } } public Vector2[] VertexVector { get { return Vertices; } } public Vector2 Scale { get { return paddleScale; } set { paddleScale = value; NormalsToEdges(this.isLeftPaddle); } } public float X { get { return paddlePosition.X; } set { paddlePosition.X = value; } } public float Y { get { return paddlePosition.Y; } set { paddlePosition.Y = value; } } public float Width { get { return (Scale.X == 1f ?

} Thanks in advance for any tips on the 4 issues. EDIT1: Something isn't working properly. The collision axis doesn't come out right and the interpolation also seems to have no effect. I've changed the code a bit: private bool ShapesIntersect(Paddle paddle, Ball ball) { overlap = 1000000f; //large value overlapAxis = Vector2.Zero; MTV = Vector2.Zero; foreach (Vector2 ax in Axes) { float[] pad = paddle.ProjectPaddle(ax); //pad0 = min, pad1 = max float[] circle = ball.ProjectBall(ax); //circle0 = min, circle1 = max if (pad[1] < circle[0] || circle[1] < pad[0]) { return false; } if (Math.Abs(pad[1] - circle[0]) < Math.Abs(circle[1] - pad[0])) { if (Math.Abs(overlap) > Math.Abs(-pad[1] + circle[0])) { overlap = -pad[1] + circle[0]; overlapAxis = ax * (-1); } //to get the proper axis } else { if (Math.Abs(overlap) > Math.Abs(circle[1] - pad[0])) { overlap = circle[1] - pad[0]; overlapAxis = ax; } } } if (overlapAxis != Vector2.Zero) { MTV = overlapAxis * Math.Abs(overlap); } return true; } And part of the Update method: if (ShapesIntersect(paddleRight, ball)) { isColliding = true; if (MTV != Vector2.Zero) { ball.X += MTV.X; ball.Y += MTV.Y; } //test if (overlapAxis.X == 0) //collision with horizontal edge { } else if (overlapAxis.Y == 0) //collision with vertical edge { float factor = Math.Abs(ball.ballCenter.Y - paddleRight.Y) / paddleRight.Height; if (factor > 1) factor = 1f; if (overlapAxis.X < 0) //left edge? ball.Speed = ball.DEFAULTSPEED * Vector2.Normalize(Vector2.Reflect(ball.Speed, (Vector2.Lerp(new Vector2(-1, -3), new Vector2(-1, 3), factor)))); else //right edge? ball.Speed = ball.DEFAULTSPEED * Vector2.Normalize(Vector2.Reflect(ball.Speed, (Vector2.Lerp(new Vector2(1, -3), new Vector2(1, 3), factor)))); } else //vertex collision??? { ball.Speed = -ball.Speed; } } What seems to happen is that "overlapAxis" doesn't always return the right one. So instead of (-1,0) i get the (1,0) (this happened even before i multiplied with -1 there). Sometimes there isn't even a collision registered even though the ball passes through the paddle... The interpolation also seems to have no effect as the angles barely change (or the overlapAxis is almost never (-1,0) or (1,0) but something like (0.9783473, 0.02743843)... ). What am i missing here? :(

• Touchpad stopped working after suspend, never woke up again

  - by Luca

  I have a Toshiba L650, installed (dual boot) Ubuntu 10.10. Touchpad worked fine until I tried for the first time to suspend (I closed the screen on the keyboard). The system never woke up again. Reset (battery disconnected and then reconnected), restart of the system, disk checks, and so on. After that, everything works fine except the Touchpad, completely dead. Rebooted again. The problem persists. Any hints? Thanks, Luca.

• Did 12.04 just add multi-touch gesture support mid-release?

  - by adempewolff

  I was reviewing the updates I was about to download today and I noticed that a lot of them had to do with gesture support, noticed that many of these were new installs rather than upgrades. Has 12.04 just added multi-touch gesture support mid-release? If so, what are the capabilities that this adds? Which applications already support these capabilities and can I expect others to add support in the near future? Here are the packages that were installed: Install: libframe6:amd64 (2.2.4-0ubuntu0.12.04.1), libgeis1:amd64 (2.2.9.2-0ubuntu1), libgrail5:amd64 (3.0.6-0ubuntu0.12.04.01, automatic) And here are those that were upgraded (also including many with touch support): Upgrade: libgrip0:amd64 (0.3.4-0ubuntu2~ubuntu12.04.1, 0.3.5-0ubuntu1~12.04.1), eog:amd64 (3.4.2-0ubuntu1, 3.4.2-0ubuntu1.1), ginn:amd64 (0.2.4-0ubuntu1, 0.2.4.1-0ubuntu1) Of which the descriptions for the new installs are, libgeis1: Gesture engine interface support A common API for clients of a systemwide gesture recognition and propagation engine. libframe6: Touch Frame Library This library handles the buildup and synchronization of a set of simultaneous touches. The library is input agnostic, with bindings for mtdev, frame and XI2.1. libgrail5: Gesture Recognition And Instantiation Library This library consists of an interface and tools for handling gesture recognition and gesture instantiation. Applications can use the grail callbacks to receive gesture primitives and raw input events from the underlying kernel device. And the descriptions for the upgraded packages are, ligrip0: provides multitouch gestures to GTK+ apps Libgrip hooks gesture recognition into GTK+ applications. ginn: Gesture Injector: No-GEIS, No-Toolkits A daemon with jinn-like wish-granting capabilities: it gives applications the ability to support a subset of multi-touch gestures without having to integrate GEIS or multi-touch GTK/Qt libs. Adding in a ton of new libraries and upgrading the existing components makes me wonder if 12.04 is meant to start natively supporting gestures other than two finger scroll in the near future. I expected these capabilities to be introduced soon but I thought that they would only be rolled out in a new release, not as upgrades for an existing release. Anyone have any info about this?

• Non-disruptive desktop-clock?

  - by YSN

  Hello, is there a clock application, that can be placed on your screen like a widget staying always on top but automatically fades away on mouseover enabling you to click through it on items below, (behaves pretty much like the Ubuntu notifications). I am aware, that there are screenlets and gdesklets widget apps, but those are buggy, look outdated, and do not comply with the criteria listed above. What I have in mind is a clock that is large, (digital), always visible (on top of all other windows), and does not disrupt your work (e.g. you can still click that scroll bar or button if it is just below the clock, since the clock fades away on hovering). Thanks in advance, YSN

• OSD desktop-clock that does not get in your way?

  - by YSN

  Hello, is there a clock application, that can be placed on your screen like a widget staying always on top but automatically fades away on mouseover enabling you to click through it on items below, (behaves pretty much like the Ubuntu notifications in that sense). I am aware, that there are screenlets and gdesklets widget apps, but those are buggy, look outdated, and do not comply with the criteria listed above. What I have in mind is a clock that is large, (digital), always visible (on top of all other windows), and does not disrupt your work (e.g. you can still click that scroll bar or button if it is just below the clock, since the clock fades away on hovering). A tool called "OSD-Lyrics" that show lyrics for songs and behaves exactly the way I described above. So it should be possible (and even easier) to do the same with a clock. Thanks in advance, YSN

• ThinkPad TrackPoint Buttons Not Working Well

  - by Oscar Godson

  The TrackPoint itself works fine. But the three buttons below the spacebar don't. For example if I were to copy these lines, 1-10, using trackpoint buttons it'd start highlighting at 7. If I use the main TrackPad (the part every laptop) and it's buttons it works normal, 1-10: 1 2 3 4 5 6 7 8 9 10 It's like the button doesn't register right away. I use the TrackPoint ALL the time. I love it and I don't think I can go back to the normal TrackPad, so is there anyway to fix this? An app or setting? Also, the middle button to scroll isn't working at all I tried: Middle Button on ThinkPad Not Working with 10.10 update And put it in /usr/share/... and /usr/lib... neither seem to work. They USED to work. I used to be able to use that method of fixing it, but it seems in 11.04 this doesnt work? I dont wanna give up on Ubuntu yet...

• Cursor (touchpad) moves and clicks erratically

  - by James Wood

  Sometimes (usually after two-finger scrolling) the touchpad on my Asus X54C becomes unresponsive and the cursor begins to click and move small distances. Clicking seems to happen more often than moving. Unlike with other similar problems, I've never seen the cursor move to (0, 0). Suspending (closing the lid) and unsuspending doesn't help, and neither does moving to a tty and back or rebooting. I've also tried disabling the touchpad via Fn+F9. That tends to take a long time, but doesn't have any effect. I'm on 13.10 at the moment, but I remember it happening on 13.04 as well. Here's the pointer section of xinput: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? ETPS/2 Elantech Touchpad id=12 [slave pointer (2)]

• Best keyboard to use with RollerMouse

  - by jrdioko

  I recently purchased a RollerMouse, which seems like an excellent way to eliminate pain caused by mousing. My question is: what good keyboard can other programmers recommend that would work well with it. I currently have a Microsoft ergonomic keyboard, but the curve and large wrist rest make it hard to use with the RollerMouse. By "good", I mean: Works with the RollerMouse (no wrist rest) Ergonomic (a slight curve or other features designed to be easy on your wrists/arms) Good for programming (that would be its primary use, no need for fancy media buttons or anything like that) Suggestions?
