[Desktop-packages] [Bug 1567841] Re: One of my two graphics cards has started to freeze the screen
I have tried the daily-current, and I could not reproduce the bug by running it for 20 hours, and usually I can trigger the bug within an hour. But, I could get the livecd to match my current setup exactly. For one thing it uses unity and not gnome-shell, and I can't install things temporarily with apt-get. So I had to use a statically compiled chromium instead of google chrome. I have found two ways of triggering the bug, and it is still there on "Ubuntu 14.04.5 LTS", and that is by letting one of these two links run for a long time in google chrome. http://xkcd.com/1663/ or https://vicandblood.itch.io/dopesmoker And it only happens with Chrome and not Firefox. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1567841 Title: One of my two graphics cards has started to freeze the screen Status in xorg package in Ubuntu: Expired Bug description: I run a setup of 2 radeon graphics cards, with 3 screens, in the following layout from left to right counting from 0: Card 0 Screen 1, Card 1 Screen 0, Card 0 Screen 0 rotated ccw I have been running this setup for a year and it has worked fine. This monday I updated some packages and did a reboot, and I usually reboot just once a month cause I patch my running kernel with uptrack. After the reboot I started noticing problems with the second card, Card 1 above. With a mean time between failures of about an hour, the second card freezes the screen, I usually notice that the mouse pointer isn't visible anymore when I move it across from one screen to the middle one. For future reference, the window I have on the middle screen is a fullscreen emacs window. I have tried the following kernels: vmlinuz-3.13.0-77-generic, vmlinuz-3.13.0-79-generic, vmlinuz-3.13.0-83-generic All have the same problem. And nothing shows up in dmesg when the freeze occurs, or in the Xorg.0.log, I made copies from before and after a freeze. If I move the mouse, that I can't see, onto the middle screen, make emacs the active window (again I can't see this), scroll around a bit with the arrow keys and take a screenshot, the screenshot shows the correctly scrolled window, so the big X buffer is actually correctly updated. If I CTRL-ALT-L to lock the screens, they all go black, but when you press enter only the screens on Card 0 shows the lock screen, the middle one again shows frozen emacs. CTRL-ALT-F1 shows two text terminals on the outermost screens, in the middle, you've guessed it, frozen emacs. If I go to the menu and select Switch user, surprise! Now the frozen screen is gone and it is a gray login screen with the login menu actually on the screen to the right. Log back into my still running user, boooh, it again shows the same frozen emacs. Switch to a completely new user, screen in middle is correct and working. And lastly if I log out completely from my user and log in again the screen is now unfrozen, but I have lots of work and it is really really annoying to have to log out 8 times during a day at work. I'm gonna try one more ancient kernel just to see if there have been some changes to drm or the radeon driver, but I am pretty stumped on this one. It all worked fine last week.
