That is very strange. What version of the kernel do you use? Do you use the frame-buffer device? I used to have a problem on my Thinkpad T20 with X server version <=4.0.2 which meant that Fn-F7 would do nothing at all if I was in X. This was very strange because I could switch to a console and Fn-F7 would work perfectly. At the time I was using the FBDEV X server, so having two FB applications operating in different ways was quite weird. I am not certain that my problem was solved by upgrading the X server, I was also tracking the new kernels at the time and it could have been a kernel upgrade. It works fine now with kernel 2.4.4 but broke with ~2.4.0. I hope this helps your investigation. -- http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/projects.html Projects I am working on http://www.coker.com.au/~russell/ My home page
