Yes, that is nice to have. > The output of 'xrandr --verbose' was identical from before to after the > VT switch. I diffed the results and got null output. I'll attach one > of the output files. I'm not actually all that surprised there, (even if it was some weird RandR thing, the output from xrandr is not too verbose). > Moreover, I've done most of my testing by just killing the display > manager and starting X with xinit, and then doing 'twm &' at the shell > prompt in xterm. OK. So that eliminates the desktop environment as a cause. > By the way, do you have access to hardware on which this anomaly can be > reproduced? Hmm... are you suggesting that I should perhaps ask for more giant LCD panels. I think I like the way you think. :-) Seriously, though, I will try to setup such an environment and see if I can replicate the behavior. > By the way, I don't mind grabbing the relevant source and building for > debug output, if that would be of any help.

If you're interesting in building things, one thing you might do is to build a recent kernel and use kernel modesetting, (load the i915 module with the option "modeset=1" either on the modprobe command line or by putting "i915 modeset=1" into /etc/modules). It would be interesting to hear if the behavior is identical with a KMS setup. -Carl -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
