Public bug reported: Binary package hint: xserver-xorg-video-ati
It is tricky to determine if this issue is the same as one reported in the several bugs about freezes / black screens, so I'm making a new one... I installed a amd64 ubuntu lucid lynx beta1 system on a box with a Foxconn mainboard that features integrated radeon graphics, namely RS690. The system has all current updates as of last saturday. I notice some things, possible related to the final freeze/crash/whatever: 1. Multiple flickering on startup, sortof in intervals of about a second. This includes the plymouth splash screen and the desktop after it appeared (automatic login) for some time. Annoying but not fatal as such, as it seems to stop, generally (maybe reappears once on certain actions, like starting a video player). 2. There is only a VGA connector and there the monitor is connected. The radeon driver complains about bad EDID data for the DVI port, multiple times. Well, there is no physical DVI port. 3. After some undetermined time of usage, the screen suddenty goes black, and I am unable to reach a console. I need to have a second computer to get debugging, I guess. The machine is not frozen, but the screen is gone. This persists with a self-built 2.6.33.2-rt13 kernel (since this is supposed to be an audio workstation) in the same manner, with the linux- rt kernel it was a bit different (for example, I needed to fix the resolution in xorg.conf because with that kernel a wrong one is detected), I did not spend enough time with it to trigger that black screen ... or indeed it does not happen there. I'll try starting with nomodeset ... then examine if there are still options like switching back to XAA (that worked in the past for the buggy intel drivers) ... or resort to VESA. I actually have no time to debug Xorg issues on that box, but well... do I have a choice? With another non-ubuntu system (older Xorg at least, kernel version about the same), this never occured. So it might have to do with the recent enable of KMS, or acceleration architecture updates. ** Affects: xserver-xorg-video-ati (Ubuntu) Importance: Undecided Status: New -- [RV690] flicker on startup, dead black screen after some time with lucid https://bugs.launchpad.net/bugs/561301 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati 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
