I have two Thinkpads, a T430s and a T450s. Both have Arch installed, the 450s also has an i3 EOS install. Since the first of the 5.10.x kernels arrived, I’ve had some problems with the T450s. Prior to 5.10.4, it would sometimes start lighdm in a very low resolution mode (looked like 640x480 instead of the 19200x1080 native mode). With 5.10.4, it would only start in that mode. Once X started, the resolution would go back to normal, but the mouse pointer would be locked and neither thinkfinger or touchpad would have any effect. Booting using the lts kernal or going back to 5.9.14 both worked without problems, but nothing helped with 5.10.4.
Found a suggestion that problems might be caused by Xf86-video-intel, so I uninstalled it. That helped, but only by making it possible for me to get to a console and shutdown from there (with it installed, attempting to go to a console just resulted in a flashing cursor).
I updated to 5.10.5 yesterday, thought the problem was gone, since the first few times I rebooted, both thinkfinger and trackpad worked. Didn’t last long - the next morning, when I booted the machine, I was back to a non-moveable mouse pointer.
I tried plugging in a USB mouse, which worked, but isn’t a practical solution (quite apart from the fact that the thinkfinger is one of my reasons for using Thinkpads).
Is anyone with similar hardware seeing this problem? Any suggestions for diagnosing and (hopefully), fixing it?
