** Description changed: - Hello all, + What I expected to happen is a normal picture on all four of my + monitors. - What I expected to happen: - I expected a normal picture on all of my monitors. - - What happened instead: - I have a problem with xrandr, or at least with my video cards, now I'm using the ubuntu 13.04 live DVD, but if I use an up-to-date ubuntu server 13.10 installation with x.org installed, the same problem occurs. - I have three video cards, one IGP, one PCI-e and one PCI, in that order: - [CODE] - root@ubuntu:~# lspci | grep VGA + What happened instead xrandr will twitch when using a DVI-VGA adapter via ubuntu 12.04-14.04: + lspci | grep VGA 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS880 [Radeon HD 4250] 02:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV610 [Radeon HD 2400 PRO] 06:06.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV250/M9 GL [Mobility FireGL 9000/Radeon 9000] (rev 02) - [/CODE] - The IGP is connected via DVI to a 24" monitor and via VGA to a 17" monitor, all good so far. - Then I have three monitors left, two 15" VGA and one 17" vga, so to use all monitors, I have to use one DVI-VGA adapter. - No matter in what order/combination I connect the monitors to the video cards, the monitor that is connected via the adapter always flickers along with the other monitor on that same card (does not matter which card). - It seems like the two monitors have two sperate framebuffers, but by default they both show the framebuffer for the monitor with adapter, but when I move the mouse they switch rapidly from that framebuffer to the other and back. - It's hard to explain, but here are three video's showing the problem: + + The IGP is connected via DVI to a 24" monitor and via VGA to a 17" monitor, all good so far.

They're recorded with my phone, so I hope they're clear enough to see the problem. - Now I hear you ask, why do I think it's a xrandr problem, well I have the exact same setup used with zaphodhead mode and xinerama, it works but its EXTREMELY slow. - I have already tried another DVI-VGA adapter, but with the same results. - Another strange thing is that xrandr seems to think that two monitors are clones (one of which not connected): - [CODE] - ubuntu@ubuntu:~$ xrandr --verbose -

What happened instead xrandr will twitch when using a DVI-VGA adapter via ubuntu 12.04-14.04: lspci | grep VGA 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS880 [Radeon HD 4250] 02:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV610 [Radeon HD 2400 PRO] 06:06.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV250/M9 GL [Mobility FireGL 9000/Radeon 9000] (rev 02) fglrx-* in Precise did not recognize all my cards so I was unable to test it. The IGP is connected via DVI to a 24" monitor and via VGA to a 17" monitor, all good so far. Then I have three monitors left, two 15" VGA and one 17" vga, so to use all monitors, I have to use one DVI-VGA adapter. No matter in what order/combination I connect the monitors to the video cards, the monitor that is connected via the adapter always flickers along with the other monitor on that same card (does not matter which card). It seems like the two monitors have two sperate framebuffers, but by default they both show the framebuffer for the monitor with adapter, but when I move the mouse they switch rapidly from that framebuffer to the other and back. Here are three video's showing the problem: http://www.youtube.com/watch?v=tQiJADHGuZg (Top-Right monitor connected via adapter, in the same card as Bottom-Right) http://www.youtube.com/watch?v=lk9muK8f06c (Top-Left monitor connected via adapter, in the same card as Bottom-Right) http://www.youtube.com/watch?v=6Ses1jUcu2k (Top-Left monitor connected via adapter, in the same card as Top-Right) I think it's a xrandr problem because using the same setup with zaphodhead mode and xinerama, it works but its EXTREMELY slow. I have already tried another DVI-VGA adapter, but with the same results. Another strange thing is that xrandr seems to think that two monitors are clones, but one of which is not connected. xrandr --verbose log: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1199409/+attachment/3944844/+files/xrandr%20--verbose I have cut out the various supported modes, the full xrandr --verbose output is attached. As you see, VGA-2 and DVI-1 apparently are clones, but in this case only VGA-2 is connected, I don't know if that is normal. I now have connected two monitors (both 15") to VGA-2 and DVI-1, and the xrandr output has not changed, it still shows VGA-2 and DVI-1 as cloned, but the two displays still twitch as in the video's... --- .tmp.unity.support.test.0: ApportVersion: 2.12.7-0ubuntu3 Architecture: amd64 CasperVersion: 1.336ubuntu1 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity DistUpgraded: Fresh install DistroCodename: trusty DistroRelease: Ubuntu 14.04 DistroVariant: ubuntu ExtraDebuggingInterest: No LiveMediaBuild: Ubuntu 14.04 LTS "Trusty Tahr" - Alpha amd64 (20140105) MachineType: To Be Filled By O.E.M.
