I have a brand new HP G62x, 11.04 64bit installed fresh.
I have only been using Gnome Classic rather than Unity but I don't think that effects this issue. I have been searching here and ubuntuforums but haven't found a solution. I'm not exactly sure what keywords I should be using.
The problem is compiz seems to fails often. The screen flickers for a moment then recovers.(sometimes)
Usually what causes it is -
- drag and drop anything
- pop up dialog windows
- menu options that drop down
- and often simply moving a window on screen
Sometimes when compiz doesn't restart itself I am forced to drop to the console(ctrl+alt+f1) to restart gdm.
I can't imagine that I am the only one with this issue.
here's a bit of the lspci -v
$00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 1425 Flags: bus master, fast devsel, latency 0, IRQ 42 Memory at d0000000 (64-bit, non-prefetchable) [size=4M] Memory at c0000000 (64-bit, prefetchable) [size=256M] I/O ports at 4050 [size=8] Expansion ROM at <unassigned> [disabled] Capabilities: <access denied> Kernel driver in use: i915 Kernel modules: i915
Any ideas on how to clear this up? Or point me to some links that will send me in the right direction?
SideNote: I have a very similar issue on my desktop machine. The graphcs ran flawlessly from 8.04-10.10 until the upgrade to 11.04. I thought the issue was with the nVidia drivers but now that I'm having the same problem here I doubt it.
