Hi Paul,<br>
<br>
I never have experienced such a problem, but two ideas:<br>
<br>
(1) Does this also happen when starting your desktop from console
via "startx"? If not, the problem is probably lightdm related.<br>
<br>
(2) Or, try adding an appropriate hook or a driver module to your
<a moz-do-not-send="true"
href="https://wiki.archlinux.org/index.php/Mkinitcpio">[
mkinitcpio ]</a> and regenerate the initramfs; maybe do an
additional update-grub. <br>

Arch Linux Xfce installed on a T450s. Worked very well indeed up
until the first of the 5.10.x kernels. After that, I started
getting lightdm starting in a very low resolution mode
(640x480?). A reboot would usually fix it, until I installed
5.10.4. With that kernel, rebooting didn't help. If I logged in,
the resolution would go to normal when Xfce loaded, but the
mouse pointer would be locked, not moveable using the touchpad
or the trackpoint. Attempting to get to a console to shut down
didn't work - all I could get was a blinking cursor. Only way
out was to either SSH in from another machine or power cycle the
laptop. <br>
<br>
Following a hint I found, I removed xf86-video-intel, which was
a marginal improvement. Still not functional, but at least I
could get to a console to do a clean shutdown. <br>
<br>
A couple of days ago, kernel 5.10.5 arrived. At first, I thought
it had solved the problem, since I was able to log in and use
the machine normally. Didn't last though - on the next day, I
was back to having a locked mouse pointer and nothing usable
except consoles. <br>
<br>
I have tried plugging in a USB mouse, which worked, but isn't a
very practical solution - I use the laptop in a number of areas
which don't give me anywhere to put a mouse... <br>
<br>
Has anyone seen this type of problem, or have any ideas as to
how to diagnose and (hopefully) fix it? For the moment, I have
to roll back to 5.9.14 or use the lts kernel to get the machine
to a usable state. <br>

Paul. <br>
