• How do I improve my screen resolution in Windows Remote Desktop?

  - by Jeff

  I'm RDP'ing into a Win2K3 machine from a WinXP machine, and I cannot stand the low screen resolution I get on the Win2K3 box. Text is too large and the graphics/colors aren't very smooth. How do I improve this? If I right-click on the desktop of the remote machine and go to Properties - Settings, I see that the screen resolution is set to 1280x1024 (should be okay, I would think), and the color quality is Medium (16 bit) (not optimal) and I don't have the option to change either setting (because they're set in the .rdp file for the session, right?). If I move over to the Appearance tab, I see that font size is set to Normal, with no option to make it smaller. The thing is, these settings are close to what I have on the XP machine I'm RDP'ing in from. The only difference (in those settings) is the color quality, which is 32 bit. Any ideas on how I can improve the situation? Other tidbits: The graphics card on the Win2K3 machine is ATI ES1000. I think I have the latest drivers for it. I'm running VMware Workstation on the Win2K3 machine, and if I create a Win2K3 VM and RDP into it from the XP machine, the resolution is just fine.

• Ubuntu 12.10 Screensaver/blanking problem

  - by Ramon J. Strauff

  I have upgraded to 12.10 and then downgraded again to 12.04 LTS because of the screensaver or screen blanking problem. After 10-12 minutes the screen goes black/blank when i dont do anything (idle). I have tried setting in the Brightness and Lock menu that the screen should never lock or turn off if idle. This is very annoying when watching movies etc... Would be nice if someone knows this.... Thanks...

• ScreenShare: command line and observe only.

  - by Shyam

  Hi, I have a wide TV screen that is attached to a Mac Mini. I am able to use this screen as a second screen using an application like ScreenRecycler. However, Sometimes I want to demonstrate what I am doing on my box on this TV screen. As this TV is attached to a Mac Mini, I want to have a screen sharing done reversed. As I know screen share can be done in observe mode and full screen, this would be more than sufficient. Because it would be pretty useless to run it continuously, I want it on demand. For this, I want to use SSH. So the only thing I would like to know is, how do I start screen sharing in from a Terminal Session. On Windows, I could start an application by using "start notepad.exe", I am looking for something similar. Eventually, I want to make this work on other boxes too. Thanks for your help!

• Blank Screen after inactive time

  - by Hari K T

  I am using Ubuntu 11.04 , on a DELL Vostro 1510. If I am inactive for a certain time, the screen usually gets locked and the login prompt will be there. Yes sometimes I am able to see the login screen and logging in as normal. But sometimes after its locked and when the mouse or keyboard is moved also nothing happens. This is happening for the second time. And its not happening always . I can switch from one terminal to other from the locked screen with Alt + + Ctrl F1 etc . But when I switch to the graphical one with Alt + Ctrl + F7 ( from the locked time ) I can see only a blank screen. I tried once login in ( Alt + Ctrl + F1 ) and trying to startx, but it said something was locked and want to delete the lock and try. So I removed don't remember what exactly it was . But it too was not a success , I was forced to press the powerbutton. Is this a bug ? I saw some but all are happening for switching users. Never experienced after logging out, but this happens only when its locked automatically actually. Update : I strongly feel this is a Bug. As I upgraded to 11.10 , I didn't noticed the same issues. But at some point if any one has an answer, you can post it. I can approve.

• Unity Greeter login screen cuts off login options

  - by ammianus

  I have a pretty newly installed Ubuntu 12.04, using Unity. My external monitor is 1920x1080 max resolution. In the Unity desktop itself everything looks great. I have an NVidia graphics card. When I start my computer and get to the Unity greeter login screen the display is oddly formatted and the resolution seems off. It looks like a zoomed view on the larger 1920x1080 screen. As such it crops the login options off to the left hand side of the screen. So I can only just see the edge of the password box for the user I want to log in with. I can log in with one account by default by blindly typing the password, but I am unable to switch to other accounts. Is there anything I can do to fix the log in screen display so that I can see the normal login options? Note: I first noticed it when I changed my desktop background and the next time I logged in I saw the issue.

• Simple monitoring of a Raspberry Pi powered screen - Part 2

  - by Chris Houston

  If you have read my previous blog post Raspberry Pi entrance signed backed by Umbraco - Part 1 which describes how we used a Raspberry Pi to drive an Entrance sign for QV Offices you will have seen I mentioned a follow up post about monitoring the sign.As the sign is mounted in the entrance of the building on the ground floor and the reception is on the 1st floor, this meant that if there was a fault of any kind showing on the screen, the first person to see this was inevitably one of QV Offices' clients as they walked into the building.Although the QV Offices' team were able to check the Umbraco website address that the sign uses, this did not always mean that everything was working as expected. We noticed a couple of times that the sign had Wifi issues (it is now hard wired) and this caused the Chromium browser to render a 404 error when it tried to refresh the screen.The simple monitoring solutionWe added the following line to our refresh script, so that after the sign had been refreshed a screen shot of the Raspberry Pi would be taken:import -display :0 -window root ~/screenshot.jpgFinally we wrote a small Crontab task that ran on a QV Offices Mac that grabs this screen shot and saved it on the desktop, admittedly we have used a package that it not mega secure, but in reality this is an internal system that only runs an office sign, so we are not to concerned about it being hacked.*/5 * * * * /usr/local/bin/sshpass -p 'password' /usr/bin/scp [email protected]:screenshot.jpg Desktop/QVScreenShot.jpgAs the file icon updates, if the image changes, this gives a quick visual indication of the status of the sign, if for some reason the icon does not look correct the QV Offices administrator can just click on the file to see the exact image currently displayed on the sign.Sometimes a quick and easy solution is better than a more complex and expensive one.

• Change X settings to boot into laptop with non working screen using an external monitor

  - by dassouki

  My laptop committed suicide. Is there a way I can boot into my ubuntu using an external screen? Ubuntu 10.10 video: Nvidia 9500 gm i think I can get dual screen upto and until the ubuntu login screen at which point it goes back into laptop display only. Then I can just type and enter my password. The system (i assume boots into ubuntu) but I got no way of going onto the x or nvidia settings to change my display to external monitor EDIT well I booted into terminal using control shift F1 i think, and now I'm trying to reporgram x.org, but strangely it seems bland with not a lot of settings in it EDIT 2 xrandr returns "Can't open display" EDit 3 after some messing around with xrandr and xinit ... my x.org only displays one monitor instead of two in its settings although both, i.e. the laptop and external screens are both connected. EDIT 4 it seems that x.org now has a "screen" and "monitor" section, I can't seem to be able to boot linux into monitor. I get a "Monitor is not a valid keyword" in this subsection

• Setting Krypton Light to Screen Pixels

  - by Adam Jerrett

  So a few days back, I started playing around with Krypton XNA for 2D lighting in my game. I noticed in general, that spawning a light at (0,0) with Krypton causes the light to appear in, pretty much, the centre of the game screen. Is there any way to change this so a Krypton light's "starting point" at [0,0] would spawn at the top left of the screen, and thus follow the standard screen co-ordinates for position? I ask because currently I'm busy working on my game where my spawn point is [512,512]. With hard code, the closest I've got to the light being "central" to this point is the vector position [12,-20], which makes no sense and is impossible to craft, mathematically, if I want the light to move with the camera (the position [480,512] maps roughly to [10,-20]). So, is there any way to "normalise" the krypton lights to use standard screen co-ordinates? If you guys can, play around with the demo from the site and please see if you can find anything out about it. Documentation on the engine is rather scarce, so it's difficult to find anything relevant to my "pixel-perfect" need. It might just also be something in the code with regards to the matrices that I'm not fully understanding. Any help would be useful. Thanks.

• 2560 x 1600 screen resolution not available when a second monitor is attached.

  - by sgmoore

  I am running Windows 7 (64-bit edition) and have a 30" Dell 3007WFP monitor which runs at a screen resolution of 2560 x 1600. This works perfectly until I try to connect a second monitor, and then the screen resolution on the main monitor immediately drops to 1280x800 and I can't change it back up to the correct resolution until I disconnect the second monitor. The graphics card is a Nvidia Quadro FX 370. This has a dual link DVI connector (to which the 30" is connected) and a single link DVI connector. The second monitor can run at 1920x1080 and is connected using a VGA to DVI connector. Note, it does not seem to matter whether the second monitor is running at 1920x1080 or even at 800x600. Windows reports Total Available Graphics Memory: 3839MB Dedicated Video Memory: 256MB System Video Memory: 0MB Shared System Memory: 3583MB Does anyone know if this a limitation with the video card, memory, drivers, connectors or something else? If this is a limitation with the video card, can anyone recommend a PCI Express 16 card that would support at least this setup, but preferably support two 30" monitors both running 2560 x 1600. (I'm not into gaming etc, so it doesn't need to be very powerful)

• dual monitors and unity - ati radeon cards

  - by michiel

  I have a vaio laptop with an ATI Radeon video card and an external screen. I used to run dual monitors on Ubuntu 10.10 fine, but recently decided to upgrade to 11.10 via 11.04 I don't think it's the video card or the fglrx driver. It seems to be unity. When I start up, the laptop screen is normal and the external screen is all white, although I can move my mouse over it. However, the cursor becomes the big X that used to be cursor of the first versions of Xwindows. I can right click on it, and it brings up the context menu for the desktop. And then, all of a sudden, it shows my desktop background. I can continue to move my mouse over the external screen, and now the cursor is normal (little white arrow). But I can't do anything any longer (not even the context menu as before), and trying to drag a window to it (which always worked on 10.10) doesn't work. I actually really like unity. It gives me the most our of my desktop, and uses all space available, which is great. But how can I get my second screen back? I tried unity 2D, but the result is the same. Edit: I think I stumbled on this bug: https://bugs.launchpad.net/ubuntu/+source/nvidia-settings/+bug/882143

• How to Deal with an out of touch "Project manager"

  - by Joe

  This "manager" is 70+ yrs old and a math genius. We were tasked with creating a web application. He loves SQL and stored procedures. He first created this in MS access. For the web app I had to take his DB migrate to SQL server. His first thought was to have a master stored procedure with a WAITFOR Handling requests from users. I eventually talked him out of that and use asp.net mvc. Then eventually use the asp.net membership. Now the web app is a mostly handles requests from the pages that is passed to stored procedures. It is all stored procedure driven. The business logic as well. Now we are having an one open DB connection per user logged in plus 1. I use linq to sql to check 2 tables and return the values thats it period. So 25 users is a load. He complains why my code is bad cause his test driver stored procedure simulates over 100 users with no issue. What are the best arguments for not having the business logic not all in stored procedures?? How should I deal with this?? I am giving an abbreviated story of course. He is a genius part owner of the company all the other owners trust him because he is a genius. and quoting -"He gets things done. old school".

  I purchased a new Samsung Series 7 laptop, Model: 700Z5B to be exact. I have everything working great using Ubuntu 11.10, the only issue is that the 2 finger scroll on the track pad does not work. Does anyone have any pointers for what I need to do to configure it. I've looked around on the forums and have not found anything that has worked yet. I don't even see the trackpad options under the mouse and touchpad settings area.

• Ubuntu 13.10, kernel 3.11 blank screen issue with hybrid graphics

  - by Lagerbaer

  On my HP Envy, which has both an Intel on-chip graphics card and an Nvidia Geforce: *-display UNCLAIMED description: 3D controller product: GK208M [GeForce GT 740M] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: cap_list configuration: latency=0 resources: memory:d2000000-d2ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:5000(size=128) memory:b2000000-b207ffff *-display description: VGA compatible controller product: 4th Gen Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 06 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:46 memory:d3000000-d33fffff memory:c0000000-cfffffff ioport:6000(size=64) I have trouble with all newer kernels. I basically had to install 12.04 LTS and use their 3.5 kernel family to get the system to boot. The 3.8 from 12.10 or the newest 3.11 from Ubuntu 13.10 leave me with a black screen upon boot. On one occasion I did hear the "log in" sound, but the screen did not display anything. I have purged all nvidia drivers so I guess it should just use the intel drivers, but apparently this is all messed up with newer kernel versions. This is different from the other "nvidia boots into blank screen" bug in that I don't rely solely on an nvidia card. Surely the intel on-chip card should be supported and leave me with something different from a blank screen? Again, it only works with kernel versions 3.5.0-41-generic, not with the 3.11.0-12 one that ships with Ubuntu 13.10. When I go into the grub menu and change the boot options from 'quiet splash' to 'nomodeset' I am able to boot the system, but then I don't get any graphics and trying 'sudo service lightdm start' doesn't succeed (I get 100% CPU for apport, but this doesn't do anything either, so I kill it). Help, I'm all out of ideas. EDIT: Let me add that I'm using the EFI boot system and have a dual-boot installation with Windows 8.

• Couldn't pass the signin screen on ubuntu

  - by Amokrane

  I have an issue here with my computer using ubuntu 10.10 on a 64 bits machine. When I start it, I have the login screen, I enter my credentials but instead of starting the session it reloads the login screen again. I checked the disc using fsck and it seems clean. How should I proceed to diagnose and repair this issue? Thanks!

• xubuntu 12.04 screen regularly stops refreshing, refreshing resumes after un-/re-maximizing a window

  - by user68477

  My screen frequently stops completely refreshing. I can make it resume refreshing by un-maximizing/re-maximize a window or by switching workspace (the un-/re-maximizing works every time. Switching workspace sometimes has to be done a couple of times). The immediate impression is that the system is frozen: there is apparently no reaction to anything I do but interestingly window title bar will change, if I switch application with (i.e alt+tab or browse through folders) I saw an identical issue in ubuntu 10.04, though a lot less frequent, I never saw this in ubuntu 12.04 (which I have been using the last 4-5 months). After switching to Xubuntu I'm seeing this again and more frequently. The specific reason I'm not sure this is a bug: I installed gnome-control-center which dragged in tons of packages. This was while trying to fix dual-screen setup. I believe the issue surfaced after this. I later meticulously removed every package from this batch (purge) in the hope that every setting would also be removed. But the issue has persisted. Another issue happened at the same time, it may be totally unrelated but it feels as if it is the same basic issue: the screen resolution of the greeter became less than the expected 1680x1050 and often after login there's just a blank and totally unresponsive wallpaper without panel so I have to force reboot. When the login is successful it's very clear that it works hard to determine the correct resolution which is achieved after a few blink to black screens. My questions: 1) Is this a settings issue or a bug? 2) How do I begin to research the issue - could I perhaps some way reset xubuntu/xfce to default. 3) If this is a bug where would be the most appropriate place report this?

• DIY Touch Screen Mod Makes Regular Gloves Smartphone-friendly

  - by Jason Fitzpatrick

  Smartphone-friendly winter gloves are expensive (and often ugly). Skip shelling out for store-bought gloves when, armed with a needle and thread, you can turn any gloves into smartphone-friendly ones. Over at Popular Science, Taylor Kubota shares the simple trick: 1. Order silver-plated nylon thread (silver conducts electricity). This can be difficult to find in stores, but major online retailers carry it. 2. Pick a pair of gloves to modify. Although leather works, it’s harder to push a needle through. 3. Stitch the figure of a star or other solid shape onto the glove’s index finger with the thread, making sure it will contact both the touchscreen and your skin.

• Ubuntu black screen after Installation of 12.10 Live USB

  - by Lime0fHint

  My computer was made in 2004, but I'm sure it doesn't matter since it's a durable machine. So recently, I decided to breathe new life to it with Linux. I tried Lubuntu 12.10, Nope. Black screen after install. So I tried Ubuntu 12.10 when I gave up, and same exact thing. Except, this time I'm fighting for it, since Ubuntu is the best OS I've ever seen. So back on-topic, when I start the installation, it says that something is already mounted (Sda or something of the sorts) So I just figure that it's the Live USB I'm using. So I let it ignore it, and move on. The rest of the installation goes smooth, all looks fine. Then I get to the screen with the introductory to Ubuntu. Meanwhile, it's still installing, but finishing up. I'm not sure if the install actually finishes, but I do know that after a bit, the screen goes back to the desktop. The install closes and I'm back at the desktop, and the cursor is showing the "loading" symbol, as if it were still working. Then the screen goes black, with the same cursor. After that, nothing. I left it over night like that thinking it was doing something, in the morning it was still black with the cursor circling or whatever. So what could be causing this? One concern I have is that I have a Nvidia graphics card (7300 GT). I heard that Nvidia isn't compatible with Linux? I did notice that it was marked as unreconigsed by Ubuntu, so is that the problem perhaps?

• Ubuntu 12.04 Full Screen without Unity Hub

  - by Xatolos

  I couldn't find an answer for this, so I thought I would try here. My problem is, I have some games on Wine that play in full screen mode but I can't really get them in full screen mode. When they start up, they end up with the GUI's "HUD" overlapping the game which is really annoying and well kills the option to play the game. This has also happened in a few of my Linux programs as well. While I wrote its a problem with Unity, it really isn't limited to this though. I've done full screen mode on Unity and had the Unity side bar and top menu overlap, I've used Gnome and had the same issue happen, Gnome menu is in the top, Cinnamon had the same issue. Sometimes if I Alt-Tab out of it and back into the program it MIGHT remove the HUD but that doesn't always work, and lets face it, full screen mode that is killed by the GUI just isn't something that can really be ignored. Any suggestions or help would be highly welcomed. My laptop http://www.cnet.com/laptops/asus-g53jw-a1-15/4507-3121_7-34210244.html edit Seems so far to be an issue with Unity and Gnome being in 3D mode, and possibly an issue with my NVidia card and XServe (I think that was it...). Going to Unity/Gnome 2d modes seem to help with this for the moment...
