@Tim Hull: I'm afraid to make things even more complicated in this situation... But here are my results: 2.6.22-10 = no problem, 2.6.22-12 = had 1 random hangup on resume, 2.6.22-14 = no problem. Testing method: tried 5 suspend/resume cycles on each kernel with XV and glxgears. I recall I had the same hangups a couple of times before (1/20 rate or so) so it has nothing to do with intel driver recent loop fix. For me it looks like kernel + X issue and is very obscure and random. This one looks orthogonal to gray blocks. With recent fixed intel driver I have no more gray blocks problem with any tested kernel. Thanks. Are you saying that this does happen with the 2.6.22-12 kernel for you?

Re: [Bug 127101] Re: laptop hangs when switching video mode
OK - I've added a blurb to the release notes about the issue. If possible, sould some people test and make sure the graphical X setting tool can properly change the driver? I've had some problems with this, but it should work as it is a showcased feature in Gutsy. On 10/10/07, Bryce Harrington [EMAIL PROTECTED] wrote: The release notes are at https://wiki.ubuntu.com/GutsyGibbon/RC. I think it's a good suggestion to mention this issue in the Caveats section, in a short and constructive manner. Would you mind taking a shot at creating an initial draft of the text to go in here? Given the plan of putting out a release note and fixing this in a post- release update, we need to approach this bug a little differently. First, we need to focus on finding regression-free fixes or workarounds. We will have made mention of the issue in the release notes, so it would not be good to put out a fix that risks just moving the bug to a new, unknown location. Second, I think we need to ensure when we apply a fix, we have a deep understanding of *why* it works; otherwise, we won't have confidence that we're truly fixing the root cause. I posted about this issue to the xorg@ mailing list last night, to get advice. Unfortunately, there's not been very little response. So far, the best attack angle we have are Juan Pablo's backtraces. These give tangible, deep information into the issue, that could possibly identify a real solution. I'm going to be focusing on this angle. I would encourage others who wish to help solve this issue to follow Juan Pablo's approach and try to also gain backtraces like his. unggnu, thanks for investigating the angle of removing the overlay fix. However it sounds like that is more a fix for bug 141063 than this one. Also, since presumably removing the fix would result in returning the original bug that it fixed, it couldn't be considered regression-free. Jose, it's quite interesting that enabling EXA seems to reduce the frequency of the issue, and that might provide a clue. However, EXA is another new technology with its own collection of issues, and given that we're dealing with issues from immature code, I don't think it's wise to solve it by adding in more immature code without having a deep understanding of why it makes it work. Also, if it requires dropping patch 120 from xserver, we'll get that regression for XAA users. Tim, if you can identify which config variable in /etc/gdm/gdm.conf to switch, then other users could test that. However, it's hard to change gdm behavior without causing a regression somewhere, so this likely contains some regression risk as well. But it might be worthwhile to identify as a workaround, if we can get several of us to validate it. -- laptop hangs when switching video mode https://bugs.launchpad.net/bugs/127101 You received this bug notification because you are a direct subscriber of the bug. -- laptop hangs when switching video mode https://bugs.launchpad.net/bugs/127101 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: [Bug 127101] Re: laptop hangs when switching video mode
I just installed the new package, spent about 20 minutes trying to crash it with the usual methods, and I have been unable to reproduce the crashes anymore. I repeatedly suspended-to-RAM, logged out, changed VTs, and even killed the X server - with no grey block crashes. In the past, I could cause said crashes to occur after 2 or 3 minutes. So far, it seems this fixes the most severe issue - though there may be other ways of producing the grey blocks of death (like the aforementioned Xv issue).

Re: [Bug 127101] Re: laptop hangs when switching video mode
Because of this issue's importance and ability to crash systems, I just e-mailed the Technical Board to ask them to switch back to i810 as the default driver for supported chipsets in Gutsy (as was the case in Feisty). Yes, you may have to use 915resolution, but you lose the random crashes - in my opinion a good trade-off :) On 10/9/07, Peter Weissgerber [EMAIL PROTECTED] wrote: ... and now it crashed again (using my two steps to reproduce) :-( You are right, this bug is not fixed! -- laptop hangs when switching video mode https://bugs.launchpad.net/bugs/127101 You received this bug notification because you are a direct subscriber of the bug. -- laptop hangs when switching video mode https://bugs.launchpad.net/bugs/127101 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 127101] Re: laptop hangs when switching video mode
I should note that the i810 driver doesn't have this problem, so if your card supports it you can use this and avoid the crashes. You do need 915resolution, though... Devs: If this problem doesn't get fixed for final, could the default driver be set to i810(+915resolution included) for cards which support it, as was the default on Feisty (intel was available as an alternate driver)?
