[Solved] Calculator not responding (freeze), screen lock doesn't work

[debcat77]

Ever since I installed Bookworm, the calculator hasn't worked. It freezes immediately, and the dialog box "Does not respond" with the options to force quit or wait appears.

Today screen lock stopped working (Super+L). Changing shortcut doesn't work. Restart doesn't work.

Blender 4.0.2 also freezes and crashes. When I try Blender 4.0.2 on Ubuntu on my other machine, it works with problems.

I have problems with Laravel too.

Bookworm is installed on an HP ProDesk 600 G2 DM.

All things considered, this might be a Debian problem. I have no clue what to do next.

SOLUTION:

Screen lock issue:

Code: Select all

sudo dpkg-reconfigure lightdm

And choose gdm3, and then restart.

Calculator issue:

I had same problem as described in viewtopic.php?t=156345, where I had to:

Code: Select all

sudo mv /var/lib/apt/lists/ /var/lib/apt/lists-SAVE/

In order to update/upgrade to 12.5:

Code: Select all

sudo update
sudo upgrade
sudo dist-upgrade
sudo clean
sudo autoclean

Why do you think that it is a Debian problem?
Debian stable is properly tested, it is not new release, it is more than 9 months old.
So if it has several problem with freezing & crashing of various software, it is more probable hardware than software problem, IMHO.
As first I would test disk (SSD by GSmartControl) & memory (RAM by MemTest86+).

[debcat77]

Given a host of problems, I'm just pointing at the most reasonable explanation.

Let me ask you, how would a hardware problem be causing screen lock to stop working?

[ruwolf]

E.g by sending wrong instruction code to CPU?
Why other people have not these problems, if they use the same release?
Screen-locker is not rarely used software, so It cannot be only your problem if it is in current Debian, IMHO.
(BTW, I am talking about probability, not certainty, of course. RAM test and S.M.A.R.T SATA SSD self test are harmless.)

[debcat77]

Why other people have not these problems, if they use the same release?

That's a good question. I just don't see it as likely that it could be a hardware issue that creates such a specific software problem.

I'm probably gonna switch to Fedora or something, but I'll try running the tests you proposed and come back with the results.

[debcat77]

I've run Memtest (3 times, full tests) and disk test (2 short and 1 long), and they all give no errors.

I've also run debsums, which also return no errors.

A friend suggested that I run Gnome calculator in terminal, which gives:

Code: Select all

For currency conversions, it uses current exchange rates from IMF obtained from its web-site. So for these operations, it probably needs active connection to Web.

I've found out that the calculator works if I turn off my VPN. I use ProtonVPN.

UPDATE: I had same problem as described in viewtopic.php?t=156345, where I had to do:

Code: Select all

sudo mv /var/lib/apt/lists/ /var/lib/apt/lists-SAVE/
sudo apt update

Then I ran update, upgrade, dist-upgrade, clean and autoclean. Gnome calculator works, also with VPN on. Blender also seems to be more stable.

Screen lock works again, I had to run

Code: Select all

sudo dpkg-reconfigure lightdm

and choose gdm3, and restart.
