Hi, I've just installed a fresh version of 12.04 on my machine and am having terrible problems with the screen flickering/going blank for several seconds as well (it was fine with the previous 10.04 version).
lspci lists the graphics card as: 03:00.0 VGA compatible controller: NVIDIA Corporation G98 [Quadro NVS 295] (rev a1) (prog-if 00 [VGA controller]) I'm using the kernel: 3.2.0-33-generic and haven't installed any additional drivers. I'm happy to supply any additional information if it would be helpful. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/945006 Title: Screen flickers heavily after upgrading to 12.04 beta 1 Status in “xserver-xorg-video-intel” package in Ubuntu: Confirmed Bug description: When the welcome screen is displayed, the screen begins to flicker heavily, regardless of the window manager used ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: xorg 1:7.6+10ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-17.27-generic-pae 3.2.6 Uname: Linux 3.2.0-17-generic-pae i686 .tmp.unity.support.test.0: ApportVersion: 1.93-0ubuntu2 Architecture: i386 CheckboxSubmission: dbc6882dda68b8df1834d327afebfa87 CheckboxSystem: b845c366ea09c60efa3a45c1b5b21525 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None Date: Fri Mar 2 19:57:40 2012 DistUpgraded: Log time: 2012-03-02 11:17:58.558053 DistroCodename: precise DistroVariant: ubuntu ExtraDebuggingInterest: Yes, whatever it takes to get this fixed in Ubuntu GraphicsCard: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device [103c:30eb] Subsystem: Hewlett-Packard Company Device [103c:30eb] InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release i386 (20111012) MachineType: Hewlett-Packard HP EliteBook 2730p ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.2.0-17-generic-pae root=UUID=4fd44d04-58f5-4e98-96eb-7d9fed249cb2 ro quiet splash vt.handoff=7 SourcePackage: xorg UpgradeStatus: Upgraded to precise on 2012-03-02 (0 days ago) dmi.bios.date: 06/24/2009 dmi.bios.vendor: Hewlett-Packard dmi.bios.version: 68POU Ver.
