I got myself a new tft monitor, it works well in graphics mode (runlevel 5), but when I startup the system or try to switch to a console (tty1 or tty2), the monitor displays a 'out of range' message on a black screen. I can setup the monitor in yast for runlevel 5, but where do I setup the monitor for text mode? Thanks for your help peter

Youhave to add a vga=your value in /boot/grub/menu.lst This is what I have and what works with a Samsung syncmaster 172v: kernel /boot/vmlinuz root=/dev/hda2 vga=792 selinux=0 resume=/dev/hda1 splash=silent showopts # vga=xxx sets the framebuffer console to a specific resolution. # Here is a table you can use so it can help you decide # what resolution you want to use: # colour depth | 640x480 800x600 1024x768 1280x1024 # 256 (8bit) | 769 771 773 775 # 32000 (15bit) | 784 787 790 793 # 65000 (16bit) | 785 788 791 794 # 16.7 Mill.

vga=normal is the bottom line works with (almost) everything way.. It's what I use for my older servers, and anything hooked up to old and clunky monitors (like an old cranky 15inch that can only do 640x480 on every other sunday ;) ) So if the below does notwork for you, just use vga=normal
kernel /boot/vmlinuz root=/dev/hda2 vga=792 selinux=0 resume=/dev/hda1 splash=silent showopts

fx Thanks, this is the information I was looking for. The old monitor could do 1024x768, so I assumed that the new one with a resolution of 1280x1024 would work with the same vga mode (791). For some reason, this resolution appears to be working in graphics mode only, not for the framebuffer. I have to set the resolution to 788 for the framebuffer, but this might be due to the graphics card not being able to keep up the min sync frequency required by the new monitor.
Thanks again very much. Peter
