timeline of what appears in syslog and Xorg.0.log at different moments
I also noticed that there are some messages in syslog that I thought may be relevant. Here is a timeline of what appears in syslog and in Xorg.0.log when I do various things. From powersave mode, hit a key, switch to text VT and back, restart gdm and then get working login screen. CPU frequency was upped before starting these experiments.
Is this still an issue with xf86-video-ati from git master? The problem does exist with xserver that comes with Ubuntu Karmic. Dependency on CPU speed is inconclusive. There is a sure way to have a working screen, and I am using now every time now: switch to text console and before the text image appears, but not too fast, switch back to graphic screen (the time between hitting key combos must be between ca. 1 and 2 seconds, make it shorter or longer and I still have black screen). I will pull from git head and rebuild, and then report. Eugene Checked with xserver-xorg-video-ati: Installed: 1:6.12.99+git20091123.b9eb2380-0ubuntu0tormod~karmic no improvement. Please advice if I can do anything more to help debug the problem. Update: as of Ubuntu lucid, X.Org X Server 1.7.6, the problem is still here. Actually, it got worse, as with the new kernel modeset default in Ubuntu, it became impossible to make the display turn on by switching to text screen and back at carefully timed moments (see comment #9). Having set "radeon.modeset=0" in the kernel boot options, this method works again. Just reporting, FWIW. As of ubuntu maverick xserver-xorg-video-ati: Installed: 1:6.13.1-1ubuntu5 the behavior somewhat changed but is still problematic. The trick with switching to text console and back does not work. The graphic screen however wakes up after pressing a key or moving the mouse, typically after 30-60 seconds but I have measured times from 10 seconds to 5 minutes. Usable but still quite annoying. Eugene Crosser, Maverick reached EOL on April 10, 2012. For more on this, please see https://wiki.ubuntu.com/Releases . If this is reproducible in a supported release, it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal: ubuntu-bug xorg Also, please feel free to subscribe me to it.
