Re: error: no server is specified / error: no suitable video mode found

[Bart Heideck]

Hello Randy,

thank you for the good find. The bug report really looks like the problem I'm 
having. However it seems like the bug was introduced in version 2.06-6 of 
Debian. Linux Mint is based on Ubuntu, which seems to be using an older 
version. I'm using 2.06-2ubuntu7.1 and 2.06-2ubuntu14.1.

I double checked the grub.cfg and the function "load_video" should be loaded. 
Even though I can't tell if and when "x$feature_all_video_module = xy" is true 
or not.

Best regards
Bart
