Issues with GPU on ThinkPad X201t
I have a ThinkPad X201t on Void and it runs pretty nice, aside from GPU acceleration. Now since I use it for drawing I need that to work since currently Krita is very laggy when moving around the canvas. Also GPU acceleration in the settings is disabled and I can't turn it on. I've followed the documentation to the tea and installed all of the packages I need, aside from Vulkan which is not needed in my case. Games also run poorly or not at all, indicating OpenGL doesn't work. The CPU is a first-generation i7-620M with Intel Integrated Graphics.
Extra info: lspci -k | grep -EA3 'VGA|3D|Display'
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)
Subsystem: Lenovo Device 215a
Kernel driver in use: i915
Kernel modules: i915
Anyone know if there is a fix?
What really bugs me is that my X220t which is one generation newer works flawlessly and has proper acceleration. I really prefer using this one because it has a 16:10 display and the battery lasts 3x as much. Thank you in advance!
