My problem here is that in yast we based on 'hwinfo --framebuffer' to query video adapter supported mode and it's based on firmware (vbios). To use video= the listed mode should based on kernel driver (kms) returned mode like output from xrandr. We have libhd to do the generic hw detection stuff, if it supports mode detection via kms driver I think it ok to add video="" Btw can you fix it by hard-code the mode in GRUB_GFXMODE= and run grub2-mkconfig -o /boot/grub/grub.cfg? Thanks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

just tested that GRUB_GFXMODE= only influences grub2's own resolution in this case
Yes, for kernel you use GRUB_GFXPAYLOAD_LINUX, but it is exactly the same as vga=. YaST2 - Bootloader - Configure bootloader - Additional kernel parameters. Add video= there. Does it work?
unless video=800x600-16 is given on cmdline
Do you need KMS in KVM? I had nothing but problems with it and simply used nomodeset + selecting resolution in YaST2. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
