Created attachment 34772 [details] xorg log At boot selection, screen is normal. When I choose default boot the splash screen comes up and looks normal for about half a second, then it flashes and slightly changes color and constantly shakes from then on. Restarting X at the GDM prompt also comes back up shaking. See attached Xorg.0.log See https://bugzilla.novell.com/show_bug.cgi?id=572102 for detailed history. I have tried booting with a different make of monitor - still shakes. user1@localhost:~/Downloads> uname -a Linux localhost 2.6.32.10-0.4-pae #1 SMP 2010-03-29 11:58:05 +0200 i686 i686 i386 GNU/Linux user1@localhost:~/Downloads> /usr/sbin/hwinfo --gfxcard 08: PCI 02.0: 0300 VGA compatible controller (VGA) [Created at pci.318] UDI: /org/freedesktop/Hal/devices/pci_8086_42 Unique ID: _Znp.VluZtC13qh6 SysFS ID: /devices/pci0000:00/0000:00:02.0 SysFS BusID: 0000:00:02.0 Hardware Class: graphics card Model: "Intel Core Processor Integrated Graphics Controller" Vendor: pci 0x8086 "Intel Corporation" Device: pci 0x0042 "Core Processor Integrated Graphics Controller" SubVendor: pci 0x8086 "Intel Corporation" SubDevice: pci 0x0042 Revision: 0x08 Driver: "i915" Driver Modules: "drm" Memory Range: 0xff000000-0xff3fffff (rw,non-prefetchable) Memory Range: 0xd0000000-0xdfffffff (rw,prefetchable) I/O Ports: 0xf100-0xf107 (rw) IRQ: 37 (11973 events) I/O Ports: 0x3c0-0x3df (rw) Module Alias: "pci:v00008086d00000042sv00008086sd00000042bc03sc00i00" Driver Info #0: Driver Status: i915 is active Driver Activation Cmd: "modprobe i915" Config Status: cfg=no, avail=yes, need=no, active=unknown Primary display adapter: #8
I experience this as well on a GM965. It always happens to the external monitor on my laptop connected via DVI. It happens when KMS is loaded by udev, and I can fix it with a reboot or by changing the video mode with xrandr. This is does not happen all the time. I'd say perhaps 1 out of every 3 or 4 boots.
The shakes are a symptom of an underrun, usually triggered by either FBC or downclocking. Passing the i915.powersave=0 option should disable those paths, and so prevent the shakes. Upgrading to the current kernel should also fix the underruns due to powersaving, and improve modesetting for Clarkdale.
Can you try kernel 2.6.35 to see if it's fixed?
(In reply to comment #3) > Can you try kernel 2.6.35 to see if it's fixed? Regrettably my box had a hardware meltdown (I think an overheat / fan failure) and I had to replace that motherboard so I no longer have this chipset. If this is thought to be fixed in the newer kernels I am fine with this being marked as closed fixed.
Sorry to hear about your machine, thankyou for the bug report and the update. Closing as I think this issue has been fixed, and we're gradually winning the battle against Clarkdale/Arrandale.
