Back on Debian (Stretch, Gnome), I have graphic issues with my Lenovo Thinkpad X250, i5-5200U, Intel HD Graphics 5500 (Broadwell GT2).
A lot of lags appear when any application is launched, when i write something with the keyboard, the ventilation goes very fast... Sometimes, the screen is blocked, and i have to force a shutdown with the button. I have to precise that i didn't have this problem with Arch Linux (Manjaro, XFCE).
I tried altenative kernels, and the better is 4.9.0-6-amd64. Later ones are worst. I have the last Intel driver (xserver-xorg-video-intel 2:2.99.917+git20161206-1). I tried to remove it to try other drivers, but i think it didn't work, because the answer to the command
Code: Select all
lspci -nnk | egrep -A2 'VGA|3D'
Code: Select all
00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics 5500 [8086:1616] (rev 09)
Subsystem: Lenovo HD Graphics 5500 [17aa:2226]
Kernel driver in use: i915
Hope someone can help...
