• Mouse wheel speed, a permanent solution?

  - by Logan

  I would like to address an issue that has been around for a while now. The wireless mouse's wheel speed is abnormally fast on Ubuntu (as well as Mac Osx, as I have read) and the way to fix this temporarily is to unplug and plug the wireless adapter. A solution for this have been asked for in various forum topics on Ubuntu forums and also askubuntu. However the best solution for this is to re-plug the wireless adapter for the mouse. This fixes the mouse wheel speed until the next reboot. My question is, what can be done to make this permanent? Can a shell script be written, or firstly what can be causing this? If you could give me some ideas on why this problem is occurring I would happily write a shell script for it... (I am thinking if this is fixed by a simple re-plug of the adapter, maybe a shell script to disable device and re-enable it or something like that... could do the trick) I appreciate any discussions and ideas on the subjects. Here are some already discussed topics on the same subject that I've researched: Mouse wheel jumpy on scrolling Mouse wheel scrolling too fast There's a lot more than that on the net, all of them ends with re-plug solution.

• Need a new mouse: clicky scroll wheel and additional thumb-operated scroll wheel

  - by cksubs

  I'm having some carpel tunnel syndrome or RSI issues, and I need to get a new mouse. I've tried a friend's Logitech MX Revolution and it's almost perfect. I LOVE the thumb-operated scroll wheel, and I think that that alone would solve many of my hand pain issues. The problem is that it uses their newfangled smooth/click scroll wheel. It can be either smooth or clicky, and is switched by pressing in the scroll wheel. I really question Logitech's user research on that one. I've been using middle-click to open new links and close tabs for years now in my browser, and I'm not willing to give that up for this cool technology. In fact I HATE smooth scroll wheels in general, and need a clicky one. The option would be ok, but not if it's activated via the middle-click button. In closing, I'm looking for these items in my mouse: Thumb-operated scroll wheel or 'joystick'-like apparatus. Clicky, as-stiff-as-possible scroll wheel on top Normal middle-click functionality. Comfortable, preferably ergonomic design. Anyone have any suggestions? Logitech, want to get rid of that smoothing-scrolling crap so I can buy your mouse?

• my mouse scroll wheel doesn't scroll

  - by Charlie Bear

  It's only a minor thing but i can't solve it. I have a ps2 mouse on win xp sp3. the wheel has stopped scrolling in all apps however in apps that support it i can click the wheel and bring up the scrolling four way arrows and scroll that way. I've tried uninstalling the drivers and changing the wheel settings but to no effect. It obviously recognises the wheel since i can click it. Any ideas super users?!

• Developing wheel reinventing tendencies into a skill as opposed to reluctantly learning wheel-finding skills? [duplicate]

  - by Korey Hinton

  This question already has an answer here: Is reinventing the wheel really all that bad? 20 answers I am more of a high-level wheel reinventor. I definitely prefer to make use of existing API features built into a language and popular third-party frameworks that I know can solve the problem, however when I have a particular problem that I feel capable of solving within a reasonable time I am very reluctant to find someone else's solution. Here are a few reasons why I reinvent: It takes time to learn a new API API restrictions might exist that I don't know about Avoiding re-work of unfamiliar code I am conflicted between doing what I know and shifting to a new technique I don't feel comfortable with. On one hand I feel like following my instincts and getting really good at solving problems, especially ones that I would never challenge myself with if all I did was try to find answers. And on the other hand I feel like I might be missing out on important skills like saving time by finding the right framework and expanding my knowledge by learning how to use a new framework. I guess my question comes down to this: My current attitude is to stick to the built-in API and APIs I know well* and to not spend my time searching github for a solution to a problem I know I can solve myself within a reasonable amount of time. Is that a reasonable balance for a successful programmer? *Obviously I will still look around for new frameworks that save time and solve/simplify difficult problems.

• What counts as reinventing the wheel?

  - by dsimcha

  Do the following scenarios count as "reinventing the wheel" in your book? A solution exists, but not in the language you want to use, and existing solutions can't be interfaced with the language you want to use in a clean, idiomatic way. In principle you could get an existing library to do what you wanted with heavy modification, but you think it would probably be easier to just start from scratch. What you're writing has the same one-line description as stuff that's already been done, but you're targeting a different niche. For example, maybe your problem has been solved a zillion times before, but in a way that's inefficient for large datasets and your code works well for large datasets.

• Need to adjust touchpad edge scroll area

  - by MikeVB

  I have an Acer Aspire that I have dual booting XP and Ubuntu. On the Windows side, the driver allows you to set how close your finger has to be to the edge of the touchpad before it goes into scroll mode. In Ubuntu I don't have the option (at least in the GUI) to change the scroll area on the pad. Is there a conf file or other way to change this? I'm constantly getting into the scroll area during normal usage. I would like to leave it on without losing so much pad area to the scroll feature. Thanks a lot.

• Mouse wheel not scrolling in JDialog but working in JFrame

  - by Iulian Serbanoiu

  Hello, I'm facing a frustrating issue. I have an application where the scroll wheel doesn't work in a JDialog window (but works in a JFrame). Here's the code: import javax.swing.*; import java.awt.event.*; public class Failtest extends JFrame { public static void main(String[] args) { new Failtest(); } public Failtest() { super(); setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); setTitle("FRAME"); JScrollPane sp1 = new JScrollPane(getNewList()); add(sp1); setSize(150, 150); setVisible(true); JDialog d = new JDialog(this, false);// NOT WORKING //JDialog d = new JDialog((JFrame)null, false); // NOT WORKING //JDialog d = new JDialog((JDialog)null, false);// WORKING - WHY? d.setTitle("DIALOG"); d.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE); JScrollPane sp = new JScrollPane(getNewList()); d.add(sp); d.setSize(150, 150); d.setVisible(true); } public JList getNewList() { String objs[] = new String[30]; for(int i=0; i<objs.length; i++) { objs[i] = "Item "+i; } JList l = new JList(objs); return l; } } I found a solution which is present as a comment in the java code - the constructor receiving a (JDialog)null parameter. Can someone enlighten me? My opinion is that this is a java bug.

• USB Logitech Rumble Pad 2 gamepad AND Thustmaster Universal Challenge Wheel not working in wine

  - by Rick Gionfriddo

  The controller is detected by the OS, and shows up in lsusb, and I can configure it with jstest-gtk, but Live For Speed in Wine doesn't recognize it as connected. Using Lubuntu 12.04, wine version 1.5.5. P.S. - It worked on a previous install of regular Ubuntu 12.04, using the same Wine version. Have tried installing/overriding/un-overriding various DLL's through winetricks to no avail, including xact and dinput8. Since it worked in a previous install of the same version, I figured it was a configuration error, and that I should ask here as opposed to put in a bug report on winehq. EDIT: I just used both controllers in TORCS... why do they work in native games, but not in wine?

• Mouse wheel scrolling in less and vim using urxvt

  - by Adam Batkin

  I have started working with rxvt-unicode (aka urxvt) but found an issue with mouse-wheel scrolling, as compared to gnome-terminal and konsole. The mouse wheel works fine for going through the scrollback buffer, but it doesn't work for automatic scrolling in less/most or vim (though in vim, setting mouse=a makes it work, but in a very different way, which I don't have to do with gnome-terminal/konsole). Is there a way to make urxvt behave like gnome-terminal and konsole when in less and vim where the mouse wheel Just Works?

• Use mouse wheel with numpad using ahk?

  - by MrSnipyCat

  I'm on a laptop without a mouse. This means I don't have the middle mouse button/wheel. I tried to use ahk to make my numpad act like a mouse wheel with the middle mouse button. Numpad8::WheelUp Numpad2::WheelDown Numpad5::MButton The problem is that it scrolls up/down 2 times (when I click and release the button). How do I make the wheel scroll only once when I hit the button and not again after releasing it?

• Rotating wheel with touch adding velocity

  - by Lewis

  I have a wheel control in a game which is setup like so: - (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; if (CGRectContainsPoint(wheel.boundingBox, location)) { CGPoint firstLocation = [touch previousLocationInView:[touch view]]; CGPoint location = [touch locationInView:[touch view]]; CGPoint touchingPoint = [[CCDirector sharedDirector] convertToGL:location]; CGPoint firstTouchingPoint = [[CCDirector sharedDirector] convertToGL:firstLocation]; CGPoint firstVector = ccpSub(firstTouchingPoint, wheel.position); CGFloat firstRotateAngle = -ccpToAngle(firstVector); CGFloat previousTouch = CC_RADIANS_TO_DEGREES(firstRotateAngle); CGPoint vector = ccpSub(touchingPoint, wheel.position); CGFloat rotateAngle = -ccpToAngle(vector); CGFloat currentTouch = CC_RADIANS_TO_DEGREES(rotateAngle); wheelRotation += (currentTouch - previousTouch) * 0.6; //limit speed 0.6 } } I update the rotation of a the wheel in the update method by doing: wheel.rotation = wheelRotation; Now once the user lets go of the wheel I want it to rotate back to where it was before but not without taking into account the velocity of the swipe the user has done. This is the bit I really can't get my head around. So if the swipe generates a lot of velocity then the wheel will carry on moving slightly in that direction until the overall force which pulls the wheel back to the starting position kicks in. Any ideas/code snippets?

  I have a Intel Cedar Trail netbook. For graphics to work, i had to build kernel 3.1 with the drivers. I followed the steps in this document After doing that, now my graphics is fine, but my mouse scroll does not work. Is that because I have not build the kernel properly?

Also my wacom bamboo tablet is not recognized, i have installed the xserver-xorg-input-wacom drivers.

  - by Virgil

  I am facing an issue while scrolling in browsers(firefox, chrome, and opera) , scroll is jagged and slow. Also when scrolling the cpu usage spikes. I am currently running ubuntu natty(beta 1), switched from ubuntu 10.10 where the problem was worse. I am using the nvidia beta driver, which ubuntu installed automatically. My graphic card is nvidia Quadro NVS 150M. I tried running ubuntu without the effects on , but when using multiple applications at the same time xorg usage spikes again. Additional info: 2GB of RAM and an intel core 2 duo processor. Any help would be greatly appreciated. Thanks in advance!

• Emulate Mouse Wheel with Synaptics Touchpad

  - by chris

  Is it possible to make the Synaptics Touchpad driver emulate a mouse wheel when scrolling? I can use the touch pad to scroll in Windows Explorer just fine but VMware does not support it. The mouse cursor changes to indicate that scrolling is active but the VMware guest will not respond to it. Since VMware supports the scroll wheel I am looking for a workaround.

• What is the best method for implementing mouse wheel activity in Delphi VCL forms?

  - by Brian Frost

  As a long time user of Delphi 7, I've rolled my own mouse wheel handling in a few controls but lately I've noticed that some recent applications only need the mouse cursor to be placed over a control (e.g a list box or tree view) for the mouse wheel activity to cause that control to scroll. This feels nice (as opposed to having to click focus a control before it responds to the wheel. Now I've moved to Delphi 2010 I'm wondering what is the 'correct' behavior? And what can I use in Delphi that avoids me having to bodge this with my own solutions now? Thanks.

• Windows 7 Explorer - Activate mouse focus to be able to scroll in tree and file view?

  - by none

  I'd like to be able to scroll in the tree view without having to click in it. Is there a way to do this? I have once used a tool that generally gives focus to the window underneath the mouse cursor, but this caused some other glitches so I would like to achieve this without an extra tool. I also think that there are programs that embed the Windows Explorer and offer more features, including the behaviour I would like to have. But maybe a registry value change is all that is needed?

• Google Chrome mouse wheel takes keyboard focus

  - by Steve Crane

  I recently switched the default browser on all my machines from Firefox to Google Chrome. In general I’m loving Chrome but there is one behaviour that is driving me nuts. Scrolling with the mouse wheel takes keyboard focus away from the document. Here’s what happens. I’ve just opened a page or switched to a new tab and the page has keyboard focus as I can use the keyboard up/down and PgUp/PgDn keys to scroll it; no problem there. But if I then use the wheel on my mouse to scroll the page, it loses the keyboard focus and no longer responds to up/down, PgUp/PgDn, or in fact any other keyboard keys. I have to click on the page background to restore the keyboard focus. This is a minor inconvenience for scrolling but where it really drives me nuts is in Google Reader and Gmail where I use keyboard shortcuts a lot. Here I find that I scroll the article or e-mail I’m reading with the mouse wheel then get no response when I press j/k to move to the next or previous article or e-mail. I am using Windows 7 and the Chrome dev channel (version 4.0.249.43).

• Scroll wheel causes browsers + Windows explorer to go back

  - by KaptajnKold

  I use Windows 7 on a VirtualBox VM on a Mac. Lately, when I'm using any browser (IE9, Chrome or FireFox or even Windows Explorer), use of the scroll wheel followed by any movement of the mouse cursor causes the browser to go back. Very annoying. This happens when I use the scroll wheel on a USB connected mouse (brand/model unknown, since I don't have it in front of me as I write this) or when I use two-finger scrolling on the trackpad when no mouse is connected. When I connect from my VM to a remote Windows box (Windows Server 2008), I experience the same problem. I have tried rebooting the VM to no avail. I am not sure when the problem started exactly. It may or may not have been after I connected the USB mouse for the first time, but trying to unplug it and then rebooting didn't help. I have tried to google for a solution, but all I've found are people who accidentally pressed the shift key while scrolling, which will cause the browser to go backward or forward in the browser history. This however is not the problem I'm having. To be clear, in my case the browser only goes back when I move the mouse after I've used the scroll wheel. I'm at my wits end :(

• Disable CTRL+mouse wheel zooming in Chrome?

  - by Peter Nore

  I'm a normal-sighted person and I would like to view pages at 100% all the time. I use keyboard shortcuts that involve CTRL a lot, so about twenty times a day I accidentally hit CTRL at the same time that I'm scrolling, which results in the page being reflowed and repainted. This in is annoying because it can take up to 30 seconds to fix the issue, depending on how complex the site layout is. On sites with dynamic layout such as Google Docs the problem is more serious; accidentally hitting CTRL+mouse wheel corrupts the display and forces me to refresh the page entirely, sometimes causing me to loose information in the process. I would like to either decouple CTRL+mouse wheel from zoom, or disable zoom functionality altogether. This is possible on Firefox by using about:config; is there a similar way to edit detailed settings in Chrome? Would I have access to the detailed settings if I used Chromium instead of Chrome? I'll probably jump ship back to Firefox if I can't solve this problem. There is a superuser question that asks basically the same thing I'm asking, but for Firefox and Internet Explorer exclusively. Other people on the Chrome forum have had related issues, but none have the same problem. "I would really like it if I could deactivate the auto zoom in/out." had "something with laptops and Windows 7", not the feature built into Chrome. Other people have had PDF specific issues, which doesn't concern me. I've also tried searching for extensions that allow you to disable the scroll; I had hoped that "Zoom Lock" would have the ability to lock the zoom at 100% and prevent CTRL+scroll wheel from distorting the display, but it doesn't work for my use case. Google Chrome version 9.0.597.84 (Official Build 72991) Operating System: Ubuntu 10.10
