I have VM A and VM B. Both VMs are running under SP 12.4. [LIST] [_]VM A resolution in the console is 24x80 - it has been updated from 12.1 to 12.4 through the Yast Upgrade option. [_]VM B resolution in the console is 48x128 - 12.4 has been installed from scratch. [\*] [/LIST] see the attached pictures. Question: Where can I set for VM A the console resolution so it is also 48x128 characters? [COLOR="#FF0000"]VM A:[/COLOR] [COLOR="#FF0000"]VM B:[/COLOR] ---

Hi AAEBHolding, just to check if the settings actually made it to the currently active kernel, have a look at “cat /proc/cmdline” so see if the “video” parameter is listed. If it is, then at least your change was done correctly. What catches the eye is your console redirection to serial - is this the same for both VMs? Else, maybe the redirect interferes with setting the (graphics card) video mode. Regards, J ---

And, by invoking commands, grub.cfg. /etc/default/grub only contains settings, used by the generator. The actual configuration ends up in grub.cfg. Regards, J ---

Thank you J for your support. It is very strange. I have 10 SLES VM running on the XenServer host. Some of them got the larger resolution while updating to SLES 12.5 - the other didn’t. Due to the fact I will install these VM from scratch as I change the size of the root partition, the resolution becomes automatically higher. I have to face the fact that there is a point when I have to stop and I think I hit the point now. This subject isn’t supported well by SUSE like others. Again, thank you very much but I close it now.
