Public bug reported: Binary package hint: xserver-xorg-video-intel
I am using Kubuntu 8.04.1 (with all current updates installed) on an ASUS Eee 1000H mini-notebook PC. I'm also using xrandr to switch off the LCD and use an external monitor with the machine while it's on my desk. Xorg video driver is xserver-xorg-video-intel 2:2.2.1-1ubuntu13.6. Video chipset is an Intel 945GME. The problem is, if I switch from LCD to the VGA-out with xrandr, after a few minutes to a few hours, the screen will change to a single solid colour. Switching back to the LCD allows me to interact with the machine again, but VGA-out remains black when I switch back to VGA again. Sync is being output on the VGA port as the monitor is showing the resolution I set it to in the Info screen. Only rebooting the machine will allow VGA-out to work again -- simply restarting X has no effect on the VGA- out issue. I've tried enabling ForceEnablePipeA, but this had no effect on the problem. Typically, the video starts glitching when I switch from LCD to VGA-out. It's about once every few minutes, and looks like the screen has missed a sync pulse or something -- the video is shifted right (or maybe left?) a bit for around 1 video frame. This starts happening a few minutes before the video locks, but may not be related. I have a suspicion that the recent driver update pushed to hardy-updates may be the cause of this. I am going to revert to 2:2.2.1-1ubuntu12 later and see if this resolves the issue. Other people have included the following in there bug reports -- I can't see any firm requirement for the lspci dumps, but I have included them anyway as they might be helpful, if only for accurately IDing the chipset. $ lsb_release -rd Description: Ubuntu 8.04.1 Release: 8.04 $ uname -a Linux cougar.homenet.philpem.me.uk 2.6.24-19-generic #1 SMP Fri Jul 11 23:41:49 UTC 2008 i686 GNU/Linux $ lspci -nn 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GME Express Integrated Graphics Controller [8086:27ae] (rev 03) 00:02.1 Display controller [0380]: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller [8086:27a6] (rev 03) $ sudo lspci -vvvnn 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GME Express Integrated Graphics Controller [8086:27ae] (rev 03) (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.
