nasty display bugs

[flaneurb]

Mine is a Dell Inspiron 1545 laptop, Intel Core2Duo from 2009. I've upgraded the package in question without any display problems:

apt-cache policy xserver-xorg-video-intel
xserver-xorg-video-intel:
Installed: 2:2.99.914-1~exp1ubuntu4
Candidate: 2:2.99.914-1~exp1ubuntu4

I feel people can use

lspci -vvnn | grep -i -E 'vga|driver'

My output of that is below:

$ lspci -vvnn | grep -i -E 'vga|driver'
