• NVIDIA x server - "sudo nvidia config" does not generate a working 'xorg.config'

  - by Mike

  I am over 18 hours deep on this challenge. I got to this point and am stuck. very stuck. Maybe you can figure it out? Ubuntu Version 12.04 LTS with all the updates installed. Problem: The default settings in "etc/X11/xorg.conf" that are generated by the "nvidia-xconfig" tool, do not allow the NVIDIA x server to connect to the driver in my "System Settings Additional Driver window". (that's how I understand it. Lots of information below). Symptoms of Problem "System Settings Additional Driver" window has drivers, but the nvidia x server cannot connect/utilize any of the 4 drivers. the drivers are activated, but not in use. When I go to "System Tools Administration NVIDIA x server settings" I get an error that basically tells me to create a default file to initialize the NVIDIA X server (screen shot below). This is the messages the terminal gives after running a "sudo nvidia-xconfig" command for the first time. It seems that the generated file by the tool i just ran is generating a bad/unusable file: If I run the "sudo nvidia-xconfig" command again, I wont get an error the second time. However when I reboot, the default file that is generated (etc/X11/xorg.conf) simply puts the screen resolution at 800 x 600 (or something big like that). When I try to go to NVIDIA x server settings I am greeted with the same screen as the screen shot as in symptom 2 (no option to change the resolution). If I try to go to "system settings display" there are no other resolutions to choose from. At this point I must delete the newly minted "xorg.conf" and reinstate the original in its place. Here are the contents of the "xorg.conf" that is generated first (the one missing required information): # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 304.88 (buildmeister@swio-display-x86-rhel47-06) Wed Mar 27 15:32:58 PDT 2013 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Unknown" HorizSync 28.0 - 33.0 VertRefresh 43.0 - 72.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Depth 24 EndSubSection EndSection Hardware: I ran the "lspci|grep VGA". There results are: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [Quadro 1000M] (rev a1) More Hardware info: Ram: 16GB CPU: Intel Core i7-2720QM @2.2GHz * 8 Other: 64 bit. This is a triple boot computer and not a VM. Attempts With Not Success on My End: 1) Tried to append the "xorg.conf" with what I perceive is missing information and obviously it didn't fly. 2) All the other stuff I tried got me to this point. 3) See if this link is helpful to you (I barely get it, but i get enough knowing that a smarter person might find this useful): http://manpages.ubuntu.com/manpages/lucid/man1/nvidia-xconfig.1.html 4) I am completely new to Linux (40 hours over past week), but not to programming. However I am very serious about changing over to Linux. When you respond (I hope someone responds...) please respond in a way that a person new to Linux can understand. 5) By the way, the reason I am in this mess is because I MUST have a second monitor running from my laptop, and "System Settings Display" doesn't recognize my second display. I know it is possible to make the second display work in my system, because when I boot from the install CD, I perform work on the native laptop monitor, but the second monitor shows a purple screen with Ubuntu in the middle, so I know the VGA port is sending a signal out. If this is too much for you to tackle please suggest an alternative method to get a second display. I don't want to go to windows but I cannot have a single display. I am really fudged here. I hope some smart person can help. Thanks in advance. Mike. **********************EDIT #1********************** More Details About Graphics Card I was asked "which brand of nvidia-card do you have exactly?" Here is what I did to provide more info (maybe relevant, maybe not, but here is everything): 1) Took my Lenovo W520 right apart to see if there is an identifier on the actual card. However I realized that if I get deep enough to take a look, the laptop "won't like it". so I put it back together. Figuring out the card this way is not an option for me right now. 2) (My computer is triple boot) I logged into Win7 and ran 'dxdiag' command. here is the screen shot: 3) I tried to look on the lenovo website for more details... but no luck. I took a look at my receipts and here is info form receipt: System Unit: W520 NVIDIA Quadro 1000M 2GB 4) In win7 I went to the NVIDIA website and used the option to have my card 'scanned' by a Java applet to determine the latest update for my card. I tried the same with Ubuntu but I can't get the applet to run. Here is the recommended driver from from the NVIDIA Applet for my card for Win7 (I hope this shines some light on the specifics of the card): Quadro/NVS/Tesla/GRID Desktop Driver Release R319 Version: 320.00 WHQL Release Date: 3.5.2013 5) Also I went on the NVIDIA driver search and looked through every possible combination of product type + product series + product to find all the combinations that yield a 1000M card. My card is: Product Type: Quadro Product Series: Quadro Series (Notebooks) Product: 1000M ***********************EDIT #2******************* Additional Symptoms Another question that generated more symptoms I previously didn't mention was: "After generating xorg.conf by nvidia-xconfig, go to additional drivers, do you see nvidia-304?" 1) I took a screen shot of the "additional drivers" right after generating xorg.conf by nvidia-xconfig. Here it is: 2) Then I did a reboot. Now Ubuntu is 600 x 800 resolution. When I logged in after the computer came up I got an error (which I always get after generating xorg.conf by nvidia-xconfig and rebooting) 3) To finally answer the question - No. There is no "NVIDIA-304" driver. Screen shot of additional drivers after generating xorg.conf by nvidia-xconfig and rebooting : At this point I revert to the original xorg.conf and delete the xorg.conf generated by Nvidia.

• ATI graphics card overriding onboard Intel graphics

  - by Patrick

  I have an ATI graphics card with an AGP connection and a DVI port, and an Intel graphics processor on the motherboard with a VGA port. I have two monitors. When the graphics card is unplugged, I get this from lspci: 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10) 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10) When it is attached, I get this: 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10) 01:00.0 VGA compatible controller: ATI Technologies Inc RV380 [Radeon X600 (PCIE)] 01:00.1 Display controller: ATI Technologies Inc RV380 [Radeon X600] Note the absence of 00:02.0 - this is apparently causing the VGA monitor to say "No Signal" and the only the DVI display to show up in the list. I checked for problems in xorg.conf... there isn't one. I have no idea how to build one.

• Problem with external monitor on my asus u36sd laptop

  - by Abonec

  To connect my laptop to external monitor (for the dual monitor configuration) I have to perform 7 weird steps: Suspend OS (close notebook for that) Connect external monitor to vga output Open notebook and unsuspend OS (at this moment in laptop screen is native resolution but on external monitor resolution is lower than native (not same as at laptop)). Suspend OS (close notebook for that) Open notebook and unsuspend OS (at this moment laptop screen has resolution as a external monitor but external monitor has lower resolution that should be in native) Suspend OS (close notebook for that) Unsuspend OS (at this moment laptop and external monitor have native resolution which will should be) I just open and close hood of the laptop until external monitor and laptop screen become in native resolution. Adjusting monitors in displays not give me proper result. I have ASUS U36SD with optimus (disabled by acpicall) with 1366x768 screen and external monitor with 1280x1024 and latest ubuntu 11.10. How to perform laptop to work with external monitor without this weird actions?

• How to set resolution higher than maximum shown?

  - by Olivier Lalonde

  I just bought an external monitor for my laptop (Asus VH242H) but cannot set its resolution to anything higher than 1600x900. I tried both from System/Administration/Monitors and the ATI Catalyst Control Center. There was a CD that came with the monitor but it only contains a Windows installer. According to the monitor's specifications: 23.6” 16:9 widescreen with 1920×1080 resolution enables borderless Full HD 1080p full-screen video display. My graphic card is an ATI Mobility Radeon HD 4670 and the monitor is currently connected to my laptop with a VGA cable. How can I set my external monitor to its maximum resolution?

• gnome-shell failed to launch when dual monitor detected, nvidia card

  - by Terry Hu

  I installed a clean precise. I like gnome-shell so I installed it. It worked well with single monitor. But It does not work well when I go to office, plug my external monitor onto my laptop. I am using nvidia driver. Another colleague is using the same laptop, he can work well with dual monitors. His laptop is ATI graphic card. When I plug my extended monitor cable, I choose GNOME, but actually it goes to gnome 2 classic desktop environment, not GNOME 3. When I disconnect the extended monitor, restart X, I can login with GNOME3. Do I have to choose between GNOME3 and extended monitor? It's a hard choose.

• Force gdm login screen to the primary monitor

  - by Kirill

  I have two monitors attached to my video card. Primary monitor has a resolution equal to 1280x1024 and the second has 1920x1200. My gdm login screen always appears on the second monitor even if it is switched off. My question is how to force gdm to show the login screen always on the primary monitor with resolution 1280x1024? I use Nvidia GT9500 videcard in Twinview mode. I can't use Xinerama because vpdau doesn't work correclty in this mode. What I have found is that mouse pointer always appears in the center of union of the screens and center is always on the monitor with higher resolution. Login screen always shows where mouse cursor is. Now my primary monitor has a resolution equal to 1920x1080. The problem still persists, mouse cursor always appears in the right-bottom corner of the second monitor.

• Jupiter seems to break multimonitor setup

  - by Philippe

  If Jupiter is in the startup my multimonitor setup will fail. Instead of two separate desktops the monitors will be mirrored, one over the other with the smaller notebook-desktop in the larger screen: After each new log-in I have to reset the Display settings in the "System Settings..." dialogue to two not mirrored screens, the changes don't seem to be saved. Given the the entry from xsession-errors /usr/lib/jupiter/scripts/resolutions: line 42: /var/jupiter/available_resolutions_LVDS: Permission denied I assumed that it's coming from Jupiter. Infact, if Jupiter is removed as startup application the desktop settings are fine. Any idea how to solve that issue?

• Blender 2.63a window position unstable with dual monitor extended desktop

  - by Steve Smith

  I have two 1920 x 1200 HP monitors and running Ubuntu 12.10. If I set them up as an extended desktop, (both 1280 x 1024 positioned for 2048 x 1280, all my applications work fine EXCEPT Blender (even Inkscape). Blender works great on a single monitor but always defaults to a window size that uses all available real estate and it can't do that with 2048 x 1280. It launches, but jumps all over the screen. Does any know a way to start Blender in a fixed size window so it would run in just one monitor?

• Workspeace view shows first workspaces out of border at left

  - by Jeremi Roivas

  I am using nvidia-current and edited from settings my monitors so that my second monitor is at left and unity-panel shows only in my main monitor. How ever now the workspaces images have shifted so that second monitor first workpsaces are moved out of the left border and when the monitor is not turn on I can't see the the workspaces there. Sometimes programs have been moved when monitor is been flashed to the workspace shown in out of border and I have no means to move the program windows into my main workspace views. Image: http://but.fi/2em As you see the second monitor works as it should work but my main monitor is fooked. Is this possible way to fix this some how?

• AMD control center doesn't save preferences

  - by Fault

  Everytime when I edit the monitor preferences in AMD to multi-monitor or to a multidesktop, when I press save or apply the program just closes with no errors and the preferences hasn't been saved. If I try to do it via the Displays app that is built-in in ubuntu 11.10 I get the following error: The selected configuration for displays could not be applied required virtual size does not fit available size: requested=(2560, 1024), minimum=(320, 200), maximum=(1280, 1280) I don't know if it helps but my graphics card is a ATI Radeon HD 4800 and my monitors are both 1280x1024. I'm running the proprietary driver without post-release updates because I always get an error trying to install that one.

• Ubuntu 12.04 Freezes after removing the HDMI cable or changing settings

  - by euDennis

  I'm using an fresh install of Ubuntu 12.04 and I'm having some problems with HDMI. I usually use it with my TV, but since the update isn't working any more. Sometimes in 11.10 I had to execute a script to get the video and sound to work in HDMI, but it was OK. Since the update, when I connect the HDMI cable, it works, but if I make any change in the display settings (like resolution, monitor position, etc,) it freezes. And if I don't change anything, it's working in both monitors, but when I remove the cable, it freezes and even the ctrl+alt+f2 shortcut works. Any ideas for fixing this? I Googled and only found many people having problems, usually with sound.

• Can't set proper resolution with a Geforce 520

  - by D0X

  I installed the 12.04 LTS but cannot get my two monitors working. The latest nvidia-current drivers installed, but i just cant set proper resolution. My card is a geforce 520 1 DVI 1 VGA. With the nvidia drivers installed i can set the DVI monitor to 1600x1200 but the VGA no further than 1360x768 (with nvidia-settings). Without the nvidia driver (using the nouveau) it doesn't work either. This same issue i had with 11.10 and i had high hopes for 12.04.

• How to configure screens in console or create screen configuration profiles?

  - by uncle Lem

  I have two monitors and integrated GPU (Intel® HD Graphics 4600). It works fine for work or movies, but if I launch games in fullscreen mode - I get artifacts, glitches and so on. Temporary disabling second monitor solve this problem, but then I have to enable it back, and set its properties manually (by default, additional screen attaches its left-top corner to main monitor's right-top corner, but I need it to be left-bottom and right-bottom corners). So I need some kind of automatization here. Best option - tool to create and swap between some kind of config profiles. Or, maybe, some console manipulations which I can put into script files would be fine too. (Ubuntu 13.04, if it matters)

• Double X-screens on one monitor

  - by user75226

  I have two monitors connected currently, my laptop display and an old dell monitor. For some reason one monitor (the dell) has double everything (it will make sense when you see the image). I think it came about when one day I tried using separate x-screen instead of just twin view for a specific reason I don't remember why (I was trying to get the Menu bar to show on my laptop monitor instead of the Dell I believe, it only shows up on the left-most monitor it seems) but anyhow I was wondering if anyone can help me fix this issue. Thanks.

• How do I reset my display settings from the command line?

  - by Trevor

  I'm running 12.10 on a dell e5400 laptop and I used xrandr to get the dual monitors working that I connect through a laptop dock. I used xrandr again to switch back to the laptop display when I undocked. The problem is, after a restart, the laptop seems to want to come back up with the dual monitor configuration and the laptop screen stays blank. I can boot into single user mode but I'm not sure what to do from there to get the display settings reset. Any ideas? There's no xorg.conf file so I'm not sure where the settings are stored anymore. Thanks.

• EVGA GTX650Ti Boost / Ubuntu 12.04 / 2 X-Star WQHD

  - by user210045

  I bought 2 X-Star WQHD monitors which, predictably, did not work with my on board video card. Yesterday I installed the EVGA card and have been trying to get the NVIDIA drivers to work. I tried to install the 304 .run, I tried to remove that and then install the nvidia-current, then I tried to activate the proprietary driver from within Ubuntu...for the first couple of attempts, I was able to see 800x600 or something close on the X-Star displays but now all I see is flashing colors on those. On my older Samsung monitor (S22B300B 21.5") is still displaying through the EVGA card. Any thoughts on how to go about fixing this?

• 3 or 4 monitors with Nvidia and Ubuntu

  - by Jason

  I saw that you are (were?) running 4 monitors with Ubuntu 8.10 and two Nvidia cards (http://stackoverflow.com/questions/27113/how-to-use-3-monitors). I was curious if you were doing this with Xinerama, a hacked up TwinView config, or multiple X screens, or some other method? Does it work with compiz? I intend to run my Dell 30" in the middle with two 1280x1024 on the sides and continue to use one X screen, and run compiz, on Ubuntu 9.04. Currently, I am using 2 monitors with twinview and compiz, which runs fantastic. I just can't get the third monitor running (unless I enable it in its own X screen, and then enable Xinerama to enable windows to be dragged as if all one X screen, but this breaks compiz, and I don't care much for having separate X screen). I am very interested in knowing how you set up 4 monitors with 2 GPU's. Thanks!

• Multiple displays using AMD drivers

  - by Halik

  I am currently running a dual display setup with nVidia 8800GTS video card, on a Ubuntu 12.10 box. The current setup uses nVidia TwinView to render the image on a 1920x1200 display and 1600x1200 one. I'm planning to add a third, 1280x1024 display to the setup. The change will require me to upgrade my GFX card to one supporting triple displays. I'll probably go with Sapphire Radeon 7770 (FLEX edition, to avoid additional active DP-DVI adapters). Before I invest in new GFX I wanted to ask - how well the AMD drivers will support such a setup. It does not matter whether it's fglrx or the OSS ones. If I remember correctly, when running Fedora on a Radeon x800, I had 'void' areas above and below the working area on my second display. The desktop was rendered in 1920+1280 width and 1200 height (which left 176px of vertical space accessible for my cursor and windows but not displayed on the screen - I'd prefer to avoid that). It may have very well been my misconfiguration back then. Generally, are there any solutions from AMD on par with TwinView? Or is it a non-issue at all? Also, I'm wondering about the usual stuff - hardware h264 decoding support, glitch-free flash support, any issues with Compiz/Unity?

• Windows XP over two monitors, but one of them switches off at boot... how to fix? How to switch bac

  - by jae

  When booting into XP (x64, Athlon II X2 245, 4GB RAM), my main monitor (got two 19" TFTs hooked up, two gfx cards, a 4650 (1GB, the primary monitor's on this) and a 4350 (512MB)) switches off. Logging in blind (cursor down key, typing password) gets me one screen, the secondary. Booted correctly until about two days ago. No clue what's the cause, last change was (if I don't overlook something) installing the ATI 9-12 hotfix. And booting into Windows 7, after returning from 7, it was like this. For some weird reason, I cannot start Catalyst Control Center (I right-click desktop, choose the CCC entry, the pointer changes to hourglass for a half-second... and nothing. Likewise with "Properties"... I think, as all windows open on the primary (off) screen, and no entry appears in the task bar for Properties) Completely stumped. Windows 7, same setup, works w/o a hitch. The primary monitor appears to run in some unknown, but pretty low, resolution, as the mouse pointer only moves onto it at about half-height. But, w/o CCC or display properties, I cannot check. And, obviously, not change anything. Hope this was not too long-winded. And I'm sure I still forgot essential stuff. :P

• Best way to mount 3-4 monitor like this?

  - by jasondavis

  I just purchased 2 HP 2009m widescreen monitors, they are not the biggest thing on the block, they are like 19-20" and are only around 150-200$ so I think they are perfect. I bought 2 of them just to make sure I like them, with the full intention of purchasing more to make either a tripple or quad display. I now I am stuck trying to decide, if I purchase 1 more to have a tripple display I would then like to just wrap the third monitor to either the rigth or left side, I could do this without a mount most likely pretty easy. If I decide to go with 2 more monitors to make a quad display then I would like to add the 2 new monitor directly above the 2 that I have now. So it would make a grid of 2 wide and 2 high. I have posted a few photos belwo to show them now with the 2 I have, you will notice that I have them tilted inwards to make more of a "V" shape instead of them being side by side and "STRAIGHT". Now if I decide to make thegrid of 4 then I will need to buy or build a stand to hold them all tightly together (no whitespace or gap between the grid of monitors) but I would like to still have both rows invert to make the slight "V". Do you know of any existing stands I could purchase that would hold all 4 monitors without making them be STARIGHT without the "V" shape? Any tips appreciated please, also they do have holes in the back for VESA. a few photos... (they are from iphone and lighting made them note very good but you can see what I am working with here)

• LCD monitor flicker when connected to a laptop using VGA

  - by Björn Lindqvist

  I have a dual screen setup with two AOC e2450Sw monitors connected to a laptop. The laptop has one HDMI and one VGA output. When one of the monitors is connected using VGA, it flickers or displays static noise. The flickering is fairly subtle and only visible on darker colors. But it is there and noticable and appears like horizontal lines. The problem only appears on the monitor connected to the laptop using the VGA cable. If I swap the monitors, the one connected using VGA is displaying the flicker but not the one connected using HDMI. The simple solution would ofcourse be to connect both monitors using HDMI, but since the laptop only has one VGA and one HDMI out that isn't possible. I've tried tweaking the monitor setting using the OSD menu, but it had little or no effect. Update: After several more trouble shooting hours, it seems the problem is not related to the monitor or VGA cable as the problem persists even if I swap the display with another brand and different cables. So it may be the graphics card? Intel HD Graphics 4000. The laptop is Acer Aspire E1-571.

• How to use different scaling for every monitor?

  - by Mikael Koskinen

  One of the new features in Windows 8.1 is the new "Desktop display scaling", which allows user to configure scaling per monitor. I've been trying to get this working in preview but with no success. If I configure the scaling, it always affects all of my monitors. I have two monitors, the main one with a higher resolution and the secondary with "normal" resolution. The secondary monitor is used in portrait mode. I would like to configure the main monitor's scaling as the text is currently too small. Here's how things look at the configuration screen by default: Now if I adjust the scaling, click apply and do relogin, everything is bigger. On both of my monitors. I haven't clicked the "Let me choose one scaling level for all my displays", but still the slider seems to affect both of them. If I check the "Let me choose one scaling level", the UI changes to look similar to what we have in Windows 8: Still the problem persists. The scaling is applied to both of my monitors. So, it doesn't matter if I check the box or not, the scaling is always applied to all the displays. Any idea how I could get this to work in preview? I've read some comments which seem to indicate that this should work in preview, though Paul Thurrott mentioned at his Winsupersite article that he either didn't get this to work.

• Windows 7: Dual Monitor Issue

  - by sdoca

  I have a Dell laptop with a docking station and two external monitors hooked up. I'm running Windows 7 64 bit. Originally, the two monitors were the same - Dell 1908FP. I have replaced one of them with an HP LA2405. I have set the HP 24" (1920 x 1200 connected via DVI port) as montior 1 and extended to use the Dell 19" (12080 x 1024 connected via VGA port) as monitor 2. I have set my power plan so that when the laptop is plugged in, it will turn the monitors off after 10 minutes, but it will not put my laptop to sleep. However, now that I have the HP monitor, when I unlock my laptop and the monitors come back on, all my windows are resized and shifted to the top left corner of the HP monitor as if they had been resized for display on the smaller Dell monitor. A co-worker has the exact same laptop and monitor configuration but doesn't experience this issue, so I figure there's some configuration that's different but we can't find it. I haven't been able to find any mention of a similar problem doing an internet search, but I'm not really sure what terms to use in my search. Anybody have any suggestions as to what may be causing the issue? OS setting? Monitor setting? EDIT: My laptop is using the Intel Graphics and Media Control Panel/drivers.

• Unity 3D (with Nvidia driver) becomes very slow and laggy

  - by Graham

  How can I prevent my Unity 3D desktop from becoming slow after a while, given that I have an Nvidia Quadro NVS 290 graphics in TwinView mode? The desktop starts out fast on login, but becomes slow / lagging / hesitant / high latency after a while, symptoms being spikes in CPU usage by /usr/bin/X whenever I cause any graphical activity with the mouse or keyboard (e.g. typing, changing tabs, dragging windows). The desktop remains slow even with all windows (except htop in Terminal) and extraneous processes killed. Detail: Changing tabs in Terminal takes about a second, and X spikes to 76% CPU. As I type into Firefox, X spikes to 95% CPU. Dragging Termiinal window, X goes to 70% CPU. Basically, every graphical action sends CPU usage of X through the roof. Device: Nvidia Quadro NVS 290 Driver package: binary driver nvidia-current-updates (280.13-0ubuntu5) Dual Monitors: Pair of DELL UltraSharp 1908FP in TwinView (X screen 2560x1024) OS: Fresh install of Ubuntu 11.10 amd64 Desktop with all updates.

This also happens when firefox is not running: Quadro NVS 290 has "No" thermal sensor according to sensors-detect: Next adapter: NVIDIA i2c adapter 0 at 2:00.0 (i2c-0) Do you want to scan it?
