Hi, On a minimal (e. g. without X) server install, one of the first things I do is add 'vga=788' to the 'kernel' line in /boot/grub/menu.lst, so I can use the framebuffer in 800x600 mode and have a better readability in console mode. However, I tried this on my minimal CentOS 5 install, and right after GRUB, the screen just blanks. I add that this (test) machine ran maybe a dozen other distros before, and the 'vga=788' line always did the trick. Any suggestions? Niki Kovacs -- Dyslexics have more fnu.
Not the solution, but the same topic is being discussed here: http://www.centos.org/modules/newbb/viewtopic.php?topic_id=7216 /Mats On 5/15/07, Niki Kovacs <contact at kikinovak.net> wrote:> > Hi, > > On a minimal (e. g. without X) server install, one of the first things I > do is add 'vga=788' to the 'kernel' line in /boot/grub/menu.lst, so I > can use the framebuffer in 800x600 mode and have a better readability in > console mode. > > However, I tried this on my minimal CentOS 5 install, and right after > GRUB, the screen just blanks.

This was an upstream bug/oversight and they did not include FB_VESA support in the 5.1 kernel.

E.g., they require fewer CPU cycles to scroll up? I'm using vga=775 on this machine, because 1280x1024 is the native resolution of the LCD screens, so the display is much sharper this way, and vga=773 on many other systems - both these modes are 256 colors. It seems like the 32k modes and above take longer to scroll up, but I haven't done any actual tests, it's just an impression. -- Florin Andrei http://florin.myip.org/
