[Trisquel-users] Re : Screen resolution

[lcerf]

Something I forgot to write, when you install a kernel, the other installed  
kernels are not removed. You always to keep a kernel you are sure you can  
boot.

Because it is older, the kernel you would install following the post above  
would not be the default one in the bootloader, i.e., you will need to select  
the older kernel from the bootloader's menu. If the older kernel gives you  
the correct resolution, we will then see how to make it the default one.
