Hello grml-users,
if you are using a grml2hd installation please notice, that X11R7/Xorg 7.0 is in the Debian unstable pool now. http://gravityboy.livejournal.com/2006/04/11/
There might be issues when upgrading to the new Xorg version. Not only if you are using ATI/Nvidia drivers but also if you are running a plain grml installation.
The grml-team strongly recommends to wait a few more days/weeks so problems have settled down.
Bug reports to the Xorg package can be found in the Debian BTS: http://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=xserver-xorg
Of course you can update your system if it's a testing box and want to test the new Xorg version. Any feedback which might help us on integrating Xorg 7.0 is welcome of course.
JFYI && regards, -mika-
