Mouse&keyboard randomly not responding after update to SLED12

SUSE Product Topics SLED Updates
1

I updated my HP ProBook 4525s with OEM preload SLED11 to SLED12. Looks
fine, but one issue - mouse and keyboard randomly not responding. I can
work 5 minutes or 1 hours but suddenly I lose control of OS. At the same
time, the computer does not hang, the clock is running, pictures moving,
sound is played. I can connect to SSH server and doing anything. After
some time mouse and keyboard come back responding and I can work again.
This time may be 2 minutes or 30 minutes - also randomly. I found two
regularities of come back responding (but not lose control): control
returns always if I connect to display:0 by VNC or if the screen light
out by energy saver. In /var/log/messages I has no find any correlations
of lose control…
Any suggestions?

Hi
Random events are the hardest… normally I would try creating a new
user and see if it duplicates. If it doesn’t then it’s possibly a user
remnant from the upgrade. If it shows as the new user, then system
related. Suggest you try that first and see.

Thank you for a reply Malcolm.
I followed your advice and created a new user. The issue appears again
for that user. Thus do a conclusion that the problem at the system level.
Did another experiment: I restored in VirtualBox HP Recovery DVD with my
OEM SLED 11 and upgraded it to SLED 12 by official DVD. In this VM I see
same issue - keyboard and mouse stop responding at random time and
sometime return. Then I created another VM and installed a clean SLED 12

  • there is no such problem.

Hi
So it would appear to be some remnant left over from the update…

Maybe opening a couple of terminals terminal and running the
following may glean some info;

tail -f /var/log/messages

udevadm monitor

Unfortunately no useful information from monitoring and logs I have not
received. And I found out that issue is not only for me:

Hi
So it would appear it’s an upgrade issue, many changes with this
release, btrfs/xfs, systemd, wicked etc…

I wonder if it’s tracker doing something. Can you disable the indexing
of files in Setting Search and Indexing.

Your running the radeon driver for your GPU?

Thanks for the advice, Malcolm. Unfortunately reset or disable the
trucker do not help. And yes, a use radeon driver, modern fglrx is not
suitable for my HD 4200 GPU.

Hi
If you run the following script as root user, can you post the output
for the radeon driver;

#!/bin/sh
cat /proc/modules | cut -f 1 -d " " | while read module; do \\
echo "Module: $module"; \\
if [ -d "/sys/module/$module/parameters" ]; then \\
ls /sys/module/$module/parameters/ | while read parameter; do \\
echo -n "Parameter: $parameter --> "; \\
cat /sys/module/$module/parameters/$parameter; \\
done; \\
fi; \\
echo; \\
done

If you also open a terminal, switch to root user and run the journal to
see if something shows up;

journalctl -f

When I had my HP4525s, I ran a script to set the power option to low as
well;

Have a look here;
