I don't think that bug 531590 is a duplicate of this bug since - I had the problem already in Karmic - xorg wasn't slow or using much CPU - there wasn't any frequent EDID probing going on - the issue was monitor model specific. Switching to another monitor model made the issue go away. -- [q45] Flickering corruption with KMS and DVI output https://bugs.launchpad.net/bugs/493707 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xf86-video-intel. ___ 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

[This is an automatic notification.] Thanks for reporting this bug to help making the Intel graphics driver better. We hear from upstream that a number of bugs (possibly including this one) have been fixed in the newer DRM code from the 2.6.33 kernel. I don't know if your bug is one of the ones fixed in this release, though, but we've prepared a PPA with this DRM update. Would you mind installing this, rebooting, and testing if the original issue can be reproduced with it or not? The DRM PPA is here: https://edge.launchpad.net/~apw/+archive/red Note there could be new bugs... please file these as new reports using the command 'ubuntu-bug linux' (for kernel or DRM or KMS bugs) or 'ubuntu-bug xorg' if you suspect them to be X.org issues. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Confirmed = Incomplete -- [q45] Flickering corruption with KMS and DVI output https://bugs.launchpad.net/bugs/493707 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xf86-video-intel. ___ 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

[Ubuntu-x-swat] [Bug 493707] Re: [Q45] Flickering corruption with KMS and DVI output
** Description changed: Binary package hint: xserver-xorg-video-intel On two computers of the model Dell Optiplex 760, Ultrasmall Form Factor the monitor shows some flickering kind of corruption when Xorg is started. Present when: - KMS is used, Monitor (Dell 20 2007FP) connected via DVI-I cable to the DVI-I output of the computer and DVI-D input of the monitor Not present when: - A Dell 2001FP monitor is used instead of a 2007FP (but I have tested two 2007FPs) - Monitor is connected using VGA (DVI-I to VGA adapter on computer, VGA input on monitor) - When booting a Lucid (Ubuntu 10.04) LiveUSB image (which has 2.6.32 kernel) (none of the not-present cases are thoroughly tested, so some of them may be coincidentally working when I tried it) Untested (so far): - Karmic LiveUSB image (with 2.6.31 kernel) I have observed it only once with UMS. Unfortunately I later accidentally deleted the log files for that run, and I haven't been able to reproduce it since. Since the problem seems to be related to KMS I have tried the standard Karmic kernel, the mainline build [1] of 2.6.32 and the current Lucid kernel (2.6.32-7.10-generic) and they all show the problem. Problem description: Most times (i.e. not always) when the computer is booted, some colors will have flickering blue dots at various places. It seems that some of the dots are always present while others flicker on and off. It seems that some colors are more susceptible than others, and that shows up as bands of corruption in gradients (see attached photo of Ubuntu login screen). The exact pattern is a little bit different from boot to boot, sometimes it is worse and sometimes better. On a normal single-color brown desktop there are flickering blue horizontal lines every now and then spanning the whole desktop. Sometimes also the VTs and the usplash screen shows flickering blue dots on the black background. In order to get as much debug information as possible, I'm reporting this bug with `ubuntu-bug` running the Lucid kernel and the DRM KMS debug option drm.debug=0x04. [2] The corruption is only present in the native mode (0x40 1600x1200). If I select any of the other modes available from xrandr, there is no corruption. At least once the corruption has disappeared after switching to another mode and back again. (`xrandr --output HDMI2 --mode 0x41` and then `xandr --output HDMI2 --mode 0x40`). I can't reproduce this now (on 2.6.32-7), so it may be kernel dependent. Also, the corruption does not show up on screenshots (when viewed on another computer or another resolution). As a side note, the DVI connection is reported as HDMI2 even though it is a DVI, but that is probably a separate issue. I was considering not reporting this, since I will only have access to this hardware for about one more week. However, I opted for filing a bug report it so that it may solve as a model bug report for others having the same problem.

Actually, the nomodeset workaround will probably stop working before Lucid is released, since UMS support is dropped from the -intel driver after 2.9.x, and Lucid is planned to ship with 2.10.x. palvolzetor, would you mind taking over this bug?

[Ubuntu-x-swat] [Bug 493707] Re: [Q45] Flickering corruption with KMS and DVI output
** Description changed: Binary package hint: xserver-xorg-video-intel On two computers of the model Dell Optiplex 760, Ultrasmall Form Factor the monitor shows some flickering kind of corruption when Xorg is started. Present when: - KMS is used, Monitor (Dell 20 2007FP) connected via DVI-I cable to the DVI-I output of the computer and DVI-D input of the monitor Not present when: - UMS is used (i.e nomodeset boot option) - Monitor is connected using VGA (DVI-I to VGA adapter on computer, VGA input on monitor) - When booting a Lucid LiveUSB image (none of the not-present cases are thoroughly tested, so some of them may be coincidentally working when I tried it) Untested (so far): - Karmic LiveUSB image - With a different monitor Since the problem seems to be related to KMS I have tried the standard Karmic kernel, the mainline build [1] of 2.6.32 and the current Lucid kernel (2.6.32-7.10-generic) and they all show the problem.

Adding dmesg output with drm.debug=0x0c, since that would also include mode debugging output, which sounds like something that could be relevant to this report. ** Attachment added: Output of dmesg with drm.debug=0x0c http://launchpadlibrarian.net/36544771/dmesg.txt -- [Q45] Flickering corruption with KMS and DVI output https://bugs.launchpad.net/bugs/493707 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. ___ 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
