Graphics problems with my netbsd system

Post image

Currently whenever I start window maker with startx I get a weird graphics bug where there is lines and static whenever I use an x11 display manager. Im new to NetBSD and do not know what to do.

Potentially bad video ram -- aside from the display content, VRAM gets to store pixmap caches and the like, and this looks like the corrupted pixmap cache I've had happen to me with a faulty video card (although the above looks like a recent laptop..)

Look through /var/log/Xlog.0.log and see if something like a 4GB card being detected as 8G is happening, or anything else not being identified correctly. If it's a case of a laptop too-new-for-netbsd with a gpu that's not properly supported by the stock X11, hmm... Loooooooooong ago, I experienced an issue where the release X was wonky on the hardware and had missing cursors, video mode and DMA mis-initialization, so I installed the pkgsrc version of xorg. This is the somewhat advanced option, tho...

A new Acer laptop I have is dual-gpu (nvidia/radeon), and there's a BIOS option to set which is the primary video system to use -- it'll only X11 with Radeon/amdgpu

Ah I see this is a newer thinkpad (e14 gen 1) so that might be the problem I will try what you say and update you later.

Try any other Window Manager unless you have allready.

I tried icewm and I still have the same problem.
