This suggests that we are running too close to the bandwidth limit on a single lane. On drm-intel-fixes, I've tweaked the fdi m/n calculation which may help, but that uses the same computed number of lanes. Can you first try that branch and then (if it still fails) apply this tweak to print out the details of the computation and up the lane count to 2 (increase to 3 and then 4 until the display is stable): diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_d index d9b7092..a9645fb 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -3790,6 +3790,9 @@ static int intel_crtc_mode_set(struct drm_crtc *crtc, */ u32 bps = target_clock * bpp * 21 / 20; lane = bps / (link_bw * 8) + 1; + printk(KERN_ERR target=%d, bpp=%d, bps=%d, link_bw=%d, + target_clock, bpp, bps, link_bw, lane); + lane = 2; } intel_crtc-fdi_lanes = lane; Reply at: https://bugs.launchpad.net/xserver-xorg-video- intel/+bug/680748/comments/9 On

[Ubuntu-x-swat] [Bug 680748] Re: [arrandale] flicker on LVDS laptop display with stripy patterns
Hey Dagfinn, Thanks for your interest in Ubuntu. Thanks for testing maverick during its development period. Unfortunately it looks like this bug report didn't get attention during the maverick development period. But I see there's not been more comments on the bug since the release, which makes me wonder if this is still an issue for you? If you've not seen this issue since maverick's release yourself, it may have been solved by kernel or X or other updates that occurred late in the release; if so, would you mind please closing the bug for us? Go to the URL mentioned in this bug report, click the yellow icon(s) in the status column and set to 'Fix Released'. If you no longer have the hardware needed to reproduce the problem, or otherwise feel the bug no longer needs tracked in Launchpad, you can set the status to 'Invalid'. If you are the original reporter and still have this issue, just reply to this email saying so. (Or set the bug status to Confirmed.) If you are able to re-test this against 11.04 Natty Narwhal (our current development focus) and find the issue still affects Natty, please also run 'apport-collect bug-number' while running natty, which will add fresh logs and debug data, and flag it for the Ubuntu-X development team to look at. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/680748 Title: [arrandale] flicker on LVDS laptop display with stripy patterns ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
