Bug #: 43655 Summary: Latest radeon dri driver on HD6950 with kernel 3.2 flickers Classification: Unclassified Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: critical Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: alexandre.f.demers@gmail.com
My new HD6950 flickers like hell right from the initialization. Using kernel 3.1.0 is just fine, but kernels 3.2.0-rc3 and over make the screen flicker (I can't tell for versions in between for now). Also, the screen seems shifted by a bit more than half my monitor's width.
I also have an integrated HD3200 and I have no problem at all when selecting this integrated chipset over my PCI-E 6950 with the same driver and kernel combinations.
