Summary: HP LP2465 screen is cutting in and out after upgrade to linux 2.6.28 Product: xorg Version: 7.5 Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Driver/Radeon AssignedTo: xorg-driver-ati@lists.x.org ReportedBy: twhiteh...@gmail.com QAContact: xorg-t...@lists.x.org I have a HP/Compaq 8501w with a "ATI Technologies Inc M76 [Radeon Mobility HD2600 Series]" graphics card. It has a HDMI port on the side of it which I use to plug into a DVI monitor at home and work via a HDMI to DVI cable. I was running linux 2.6.28 patched with - bdd91b2b and fb939dfc (to fix 31339), and - a0ae5864 (to fix 18564). I upgraded to 2.6.38 and, while my monitor at home continues to work okay, my monitor at work now has flickering black lines and it cuts in and out to a black screen. I did diffs of the kernel logs, xorg logs, and xrandr --verbose outputs, but nothing seemed to indicate any significant difference. Finally, I - checkout out the 2.6.38 kernel from git, - reverted to bdd91b2b (the first version that had all the above patches), and - discovered that it also had these problems, so I - did a bisect on any changes that touched the radeon directory between that and 2.6.26 (cherry picking bdd91b2b, fb939dfc, and a0ae5864 as required), and - this pointed to 48dfaaeb (drm/radeon/kms: remove new pll algo). I then did some verification of this by - attempting to revert 48dfaaeb on top of 2.6.38. However, this failed as it was not clean and I was not sure of my corrections, so I instead - reverted it on top of bdd91b2b (the first version that had all the above patches) which produced a driver that worked fine with both monitors. I presume this then means my monitor at work is having an issue with the pll settings the old new pll algorithm is generating. I don't know what information would be helpful for resolving this though, so I'll just attach - the kernel logs, - the xorg logs, and - the xrandr --verbose logs for my original patched and working 2.6.36 kernel and the non-working 2.6.38 (although I couldn't see any significant differences in these). Please let me know if there is any other information I can provide.
