Description:
When a monitor is connected with an VGA cable and an adapter at the DVI port of an ATI 1950XT, the screen turns black every 30 seconds for about a second. When starting the screen settings app of XFCE, the screen turns also black for a second. Making changes in this app like changing resolution or frequency turns the screen black permanently. When connecting the monitor directly with DVI all problems are solved. Additional info: * package version(s) * config and/or log files etc. Before this update everything worked fine: [2011-01-21 17:02] starting full system upgrade [2011-01-21 17:02] removed sip (4.12-3) [2011-01-21 17:02] removed pyqt (4.8.2-2) [2011-01-21 17:02] upgraded dmidecode (2.10-1 -> 2.11-1) [2011-01-21 17:02] upgraded ffmpeg (26387-1 -> 20110121-1) [2011-01-21 17:02] upgraded pm-utils (1.4.1-1 -> 1.4.1-2) [2011-01-21 17:02] upgraded python2-sip (4.12-2 -> 4.12-4) [2011-01-21 17:02] upgraded python2-qt (4.8.2-3 -> 4.8.2-4) [2011-01-21 17:02] upgraded upower (0.9.7-2 -> 0.9.8-2) [2011-01-21 17:02] upgraded xfce4-diskperf-plugin (2.1.0-5 -> 2.3.0-1) [2011-01-21 17:03] Running 'pacman -Scc' Steps to reproduce: See above. |

If that causes your screen to turn black, then it's a bug in the ATI kernel driver that blanks your screen when reading those status files from sysfs. It would be nice if you could give the output for both VGA and DVI like you said in your initial bugreport.
I executed your script and the screen turned black; connected to the VGA port. I'm not able to test the DVI/HDMI port.
I'm using a Intel GMA HD internal graphic card in my laptop.
I also furthermore noticed, when I execute xrandr (with and without any options) the screen turns black twice. First one directly after I used the command, second one 10 seconds later.
Tried on a Nvidia graphics card and on a Intel+Nvidia (Optimus with the Nvidia disabled - so it's on a Intel GMA something, I guess) with a CRT connected to the VGA port. Every X secconds the screen goes black for 1 seccond or so, like the reported issue, although I can change resolutions on the Gnome monitor app. This happens on both X and tty's, even during boot.
Downgrading to 0.9.7-2 fixed the issue.
Reporting upstream.

Upgrading to kernel 2.6.37 did not help me! Only killing upowerd does...
