[Trisquel-users] Resolution stuck at 1400 x 1050 after updates

[shellinflux]

Hello I have a problem. Every time I reinstall the OS and do the updates, the  
resolution is stuck at 1400 x 1050. I tried to set it to something else using  
some xrandr commands, but it didn't work. Also the package xf86 is no longer  
present when I go to synaptic package manager. I don't know if that has to do  
with anything, but I should probably update the graphic driver or kernel. I  
tried updating the kernel using jxself's guide, when I try to install the  
appropriate kernel package it's stuck at 0% downloading it. Can somebody  
please help me?
