Hi List, I have a Philips 180B2 LCD monitor on my 4-node cluster running SuSE linux 8.2. Unfortunately, this monitor is not represented in the hardware database. This is not a huge problem as it is just a 1280x1024@60Hz LCD screen and once X was configured alright I can work with it under runlevel 5. The weird thing is that it will not work under runlevel 3. In other words, when I try to switch to one of the consoles I end up with a black screen and a moving error message "cannot display this video mode, change computer display to 1280x1024@60Hz 46. 40K/86. 72 Hz". As you can imagine this makes it fun to install or upgrade... Basically I have to use a different monitor to do any fresh installation or upgrade. Then, going back to the Philips monitor I have to start up blind in runlevel 3, log on as root and start sax2 to set configure X, then start yast to reset the start-up runlevel to 5. Well, I had hoped that 9.1 would solve the issue, but unfortunately, that is not the case. So, my question is this: can I specify the correct screen resolution and refresh rates during the boot options? The grub boot menu is displayed alright and if I could only figure out what to put there on the options line I figure I'd be alright. Can someone please point me to a list with the boot options that are recognized by the suse kernels? Thank you very much, Alex.
are you able to see the boot stuff after grub times out? If not, maybe you just need to lower the console resolution (though I'm not sure about refresh rates) by editing /boot/grub/menu.lst and changing the "vga=" part of the kernel line for linux. http://www.jeepster.org.uk/bits/grub.html has a chart showing the values. try 640 and work your way up if it works? I'm not sure what you need, but you can At 10:10 AM 5/20/2004, you wrote:

Thank you for your help. Of course I had tried to put vga=normal on the options line before but didn't realize that this wouldn't work because of the showopts option that was present in my /boot/grub/menu.lst file. I found the relevant info here: http://portal.suse.com/sdb/en/2002/12/wessels_blackinst.html which suggested to take showopts out to be able to manipulate the vga settings.

vga=0x318 actually works fine, so it looks like the monitor wants to start with a little lower resolution than it is rated. Best regards, Alex.
