Thread-topic: restoretextmode crashes dom0

Hello,

I’ve just been playing around with resizetextmode/resizecons from svgalib to change my virtual terminal to 132x30 characters. This works fine under native Linux but when run from within domain 0 it causes a crash/reboot.

For example, the command “resizetextmode –w 80x25” which should save the current VGA settings to file 80x25 crashes dom0, as does any attempt to load a previously saved (e.g. under native Linux) file.

Also, is there some way to specify the VGA mode? I tried adding “vga=ask” to the dom0 boot line in GRUB and the same to Xen’s boot line but neither has any effect and Xen always boots in standard VGA mode with a 80x25 character console.

Dave
