I have a CentOS 4.3 workstation I use for experimentation on my desk at work. It was plugged into an old LG 14" monitor, and I switched the video cable to a Samsung 17" LCD without rebooting. The screen resolution was set to 800x600 on the 14" monitor, and the display worked fine at 800x600 after switching to the Samsung 17". When I changed the resolution to 1024x764, the screen went black and I haven't been able to get it back again. I hoped rebooting and having the system search for new hardware would adjust the display driver to the correct monitor but it didn't. I booted with CD1 in rescue mode and changed /etc/inittab to start in command line mode (3), but the screen still goes black after going through some initial boot processes. I suspect the issue is driver related, rather than screen resolution related. When I initially went to change the resolution, it recognized the monitor as a generic VGA, and I changed the monitor type to Samsung Syncmaster 711T at the same time as changing the resolution. How can I get the system to recognize the new monitor?
Did you try booting in runlevel <= 3 and then system-config-display --reconfig? If that works, you could set display as vanilla as you can and then start your customisation over. Also you can peek at several options with system-config-display --help -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
