Hi Urs, Yes I used 915resolution (installed via yum install 915resolution) yum list 915resolution gives me this result. Installed Packages 915resolution.i386 0.5.2-2.el4.rf installed The machine is at CERN so I am using slc4.7 which is a variant of SL4.7 When I tried to install 915resolution as a service via /sbin/chkconfig 915resolution on I get this result: error reading information on service 915resolution: No such file or directory What I have done as a work around is to change /etc/rc.d/rc.sysinit and added these lines: # Hack at end for using 915resolution echo "overriding VESA BIOS resolutions" /usr/sbin/915resolution 3a 1440 900 Of course, if initscripts package changes I have remember what I have done and change the file again. Thanks again for your help.
