-- Strange stuff for sure! I luckily never encountered troubles with
the trackpoint.<br>
<br>
Any changes booting a fallback kernel?<br>
However, running LTS instead of being bleeding edge is not the worst
idea, in the contrary. <br>
<br>
Looks like there's still a new appropriate driver missing.<br>
Or, try dis/enabling other extra options in your xorg conf; or check
it for typos.<br>
Or disable them all (if any) and try running defaults...<br>
<br>
How about <a moz-do-not-send="true"
href="https://wiki.archlinux.org/index.php/General_purpose_mouse">[
gpm ]</a>, does it work with your trackball? In case you're left
to console, it makes things like c&p easier.<br>
<br>
Another idea: If it's an Xorg problem, have a taste of wayland,
where I recommend <a moz-do-not-send="true"
href="https://wiki.archlinux.org/index.php/Sway">[ sway ]</a>, for
instance; started either by tty or a dm. It runs flawlessly in
combination with xwayland, even opengl; when I started using it, my
former (maybe also dbus related) libinput+xorg freezing problems
were totally gone. (Anyway, I still prefer my X desktop which got
revived again after another bunch of updates a year later; yet sway
is my spare one.)<br>
<br>
Good luck!<br>

Michael,
<br>
<br>
Sorry for the long delay in replying - been trying to work out
what was going on. And not getting very far....
<br>
<br>
I tried disabling lightdm and starting Xfce manuall. Made no
difference, the mouse pointer was still locked. I've also tried
looking through the Xorg log to see if there are any errors, but
nothing shows up.
<br>
<br>
One thing that I have discovered is that the freeze is normally
temporary. After 2 -3 minutes, both touchpad and trackpoint start
working. Looking through the journal, I can't find any sign of
error, other than this:

Which is around when the trackpoint and trackpad started working.
No idea what is causing it.
<br>
<br>
I am also seeing failures and restarts with lighdm on most boots
and some coredumps from xorg, though in both cases, they work
without any visible problems.
<br>
<br>
For the moment, I'm running the LTS kernel so I can actually do
some work on the machine, and trying the new 5.10.x kernels as
they come through in the hopes of the problem being fixed. I would
love to be able to work out what is going on, if only so I can
raise a bug against the relevant software.

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 [ mkinitcpio ]
<a class="moz-txt-link-rfc2396E" href="https://wiki.archlinux.org/index.php/Mkinitcpio"><https://wiki.archlinux.org/index.php/Mkinitcpio></a> and
regenerate the initramfs; maybe do an additional update-grub.

<blockquote type="cite">I have 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.
