[Ubuntu-x-swat] [Bug 758785] Re: [arrandale] Display flickers or blank on login (x86_64)
The patch Bryce noted in comment #14 should have been included upstream as of v2.6.39-rc5. That being said, just curious if you've been able to test with a newer Oneiric 3.0 kernel to confirm this is at least fixed in the actively developed kernel. We can then investigate SRU possibilities for Natty. ** Changed in: linux (Ubuntu) Status: Triaged = Incomplete -- 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/758785 Title: [arrandale] Display flickers or blank on login (x86_64) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/758785/+subscriptions ___ 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 758785] Re: [arrandale] Display flickers or blank on login (x86_64)
Hi Stefan, Just wanted to check in with you again regarding this bug. It's great that you've been able to work around the problem by using the newer kernel. Talking with Jesse Barnes (Intel upstream), a number of fixes went in to the kernel for this generation of hardware subsequent to what was pulled for Ubuntu's kernel in natty, so it sounds like we're just missing a key patch or two. [@Kernel team - might want to pick jbarnes' brain for patches worth pulling.] I think the next logical step would be to do a git bisect search on the kernel to identify what the fix was. The kernel team may have some better suggestions, but if you want to go forward with the bisection search, they've documented the procedure pretty well here: https://wiki.ubuntu.com/Kernel/KernelBisection. Since it appears this is pinpointed to the kernel rather than X, I'm going to go ahead and close out the X task at this time. I'll try to set the kernel tasks tags and such to hopefully get it on that team's radar, but you may want to ping them if you don't hear from them within a few weeks. ** Changed in: linux (Ubuntu) Importance: Undecided = High ** Changed in: linux (Ubuntu) Status: Confirmed = Triaged ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete = Invalid ** Also affects: linux (Ubuntu Natty) Importance: Undecided Status: New ** Also affects: xserver-xorg-video-intel (Ubuntu Natty) Importance: Undecided Status: New ** Changed in: xserver-xorg-video-intel (Ubuntu Natty) Status: New = Invalid ** Changed in: linux (Ubuntu Natty) Milestone: None = natty-updates ** Changed in: linux (Ubuntu Natty) Status: New = Triaged ** Changed in: linux (Ubuntu Natty) Importance: Undecided = High ** Changed in: linux (Ubuntu Natty) Assignee: (unassigned) = Steve Conklin (sconklin) -- 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/758785 Title: [arrandale] Display flickers or blank on login (x86_64) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/758785/+subscriptions ___ 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 758785] Re: [arrandale] Display flickers or blank on login (x86_64)
Hello Bryce, so after spending the past 12 hours doing fresh installs of Natty on my X201, thinking it was my corrupted install initially, and then still having the issue on a freshly installed system, and pulling my hair out trying to see what was wrong, I installed the special rolled linux-kernel that you posted in bug #761236 ( linux- image-2.6.39-994-generic2.6.39-994.201104200727 ) and it has *fixed* my external display problem. I have tested it a few times, rebooting, and coming in and out of hibernate, from internal to external display, and it works perfect. Thank you so very much for thinking of the connection to that other bug that you saw.

Bryce: Yes! Thats exactly what is happening with the flicker on my external monitor, too. I appreciate your last write-up, and was just about to give up, and do a clean reinstall of the official Natty release, because the support team here in Montreal did a clean install on exactly my machine (Lenovo X201); hooked an external monitor to the laptop, and he had no issues with switching back and forth on the internal to external monitor. I am also having other instability issues with the machine (randomly kernel- crashing on me now) so I think this would be the best option for me. Let me know if you still want me to proceed with your steps, otherwise I will just do a clean re-install in the next couple of days. I really appreciate your time and effort on this issue.

** Description changed: Binary package hint: x11-xserver-utils I upgraded my system from Maverick to Natty Beta. I take daily updates every day. Since then, When you boot the system, with the external monitor attached, the external display flickers badly and the screen is unreadable. I hit FN - F7 (Monitor Toggle) on my Thinkpad X201 to reset the display, and then I see the login screen correctly, on both internal, and external. After I log in, the same thing happens, screen flikers and unreadable on external monitor. I hit FN F7 again, and I get the 800x1024 default screen, which I then have to use 'Monitors' to increase the Resolution to the mode I like on my external monitor. This happens everytime I boot or login.

[Ubuntu-x-swat] [Bug 758785] Re: [arrandale] Display flickers or blank on login (x86_64)
Hmm. I've been looking at a number of other bug reports with Arrandale and external monitor troubles. There definitely seems to be a modesetting bug that _appears_ to be particular to arrandale (at least, the reports I've looked at are mostly all arrandale systems). However, the symptoms in those cases are quite different from yours - the screen becomes blank in one set of cases, or the X server locks up unrecoverably in the other set. I'm going to treat your bug as unrelated to those, although it couldn't hurt for you to run some of the same tests I'm having those others do, just to see if it turns up anything interesting. As to your question, monitors.xml gets generated by the gnome-display- properties applet when you Apply your settings. That applet is backed by a daemon process, gnome-settings-daemon, which I suspect may also write out the current monitor settings to monitors.xml during shut down (I'm not certain, but I think it does). The Fn+F7 key I believe is also tied into the above and handled by gnome-settings-daemon. However, historically there's been a lot of different services that have handled that hotkey, so it would probably be clearer if we could focus on a test case for reproducing the issue that didn't involve key hits. This is why I suggest trying to repro it with just the xrandr command. If you run it from console you may have to do it like DISPLAY=:0 xrandr --auto or even specify the outputs (see man xrandr for some examples). Here are some other things to test, sorry this is kind of a grab bag of random ideas: * After reproducing the issue, run `xset dpms force on`. (If this works, it suggests a DPMS issue) * Install xdiagnose and use that to turn on Debug Messages (the first checkbox). Reboot, reproduce the bug, and then (from an ssh session or console) collect the output of the command 'dmesg dmesg.txt' and attach dmesg.txt here. * Disable the VESA framebuffer from loading. This can also be done via the xdiagnose tool. * Can you describe the flicker in more detail? Can you approximate the frequency it is running at? If it is flickering at a regular rate it can suggest some other process (e.g. upowerd) may be polling the monitor; if so, killing that process may stop the flickering. (I'm doubtful of this because simply doing Fn+F7 wouldn't be enough to stop the polling; still, may be worth checking.) * You indicated this did not occur with your maverick installation. This suggests testing if you can boot on the old maverick kernel (go into grub during boot by holding down the left shift key; if it's still installed you can select the 2.6.35 kernel, if not you'll need to install it manually) and test if the issue is reproducible. (If this works, then a git bisection effort might be able to isolate what kernel change introduced the problem.) ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete = New -- 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/758785 Title: [arrandale] Display flickers or blank on login (x86_64) ___ 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
