Bug Description

Binary package hint: xorg

this is probably a known issue...but xorg chooses wrong resolution on live discs which causes bad graphical issues untill you figure out how to get the resolution lower.....for me it used to be were i could figure it out but it seems now i cant because its really messed up as shown on the jpeg i added

and usually it does the same after installing which really causes problems so it might be good to put it as safe graphics by default.

this one shown on the screenshot is from the 31-Jan-2011 daily live using a cell phone camera

for some more info im useing a HP Pavilion dv6605us with a nvidia GeForce 7150M /nForce 630M built-in graphics the max screen resolution is 1280x800 for the screen which is a 15"

it seems nouveau is part of the problem because now no matter the resolution i use i get the same graphical issues and i know that nouveau loads at default when using nvidia till a different driver is loaded for it

i did some checking by doing all of the resolutions i could by adding vga=(whatever resolution) which makes it seem to be more of a driver problem which by what i know the default for the daily live build is nouveau...

Hm. That looks pretty bad. Would it be possible for you to collect logs from a livecd which displays that problem? Running “apport-collect 711591” should collect all the relevant logs and attach them to this bug.

both using laptop screen and a screen connected to the VGA port gets the same problems on the graphics but the console is able to be seen in an ok state on the screen connected to the VGA port

well i decided to try something which proves that its xserver-xorg-video-nouveau thats causing the problem because if i add to the other options line area for booting into the live cd with "nouveau.modeset=0" the graphics show correctly

that helps for some people and iv tried that and shadowFB and a combination of them and both gave the same results of an unusable GUI....and by the looks of it its started doing this stuff sence a few patches by whats came up on the upstream bug report, so you might want to keep checking on that end too

misaligned reg sounds weird. Other than that (and a lot of other nouveau verbosity) there doesn't seem to be an obvious error message in dmesg, nor anything in /var/log/Xorg.0.log to indicate that the system was in a broken state.

Are you certain you did apport-collect while the system was exhibiting the issue?

Given that they're looking at kernel patches in the upstream bug report, that suggests this is a linux kernel drm bug. Which makes sense since -nouveau relies on kernel modesetting. Refiling to linux. Nevermind my last comment.

On the upstream bug a preliminary patch is suggested. I have pulled this patch into the Natty kernel for testing. Could those of you affected by this bug give the kernels with this fix a test and report back here. The kernels are at the URL below:

the patch fixes it were now i can see for the most part but it doesnt fix what was going on befor the compleate blocking of the screen

still has a small tiling of about 3 or so when resolution is at 1280x800(16:10) which i believe is my screens native resolution....that tiling is fixed by lowering the resolution which i now have at 1024x768(4:3)

it seems to have the small tiling when the aspect ratio is at (16:10) and (9:5), all resolutions using the aspect ratio (4:3) shows things perfectly when using the patch
