xcalc and xlogo kills X server

[Member devilalice]

Hi ! Got an interesting trouble. Most probably, not AntiX related, but let me share the experience.

I decided to launch old good xcalc (AntiX 19 32bit) and it immediately killed the X session. I tried launch it several times and it happened every time. Beside xcalc the same behavior is for xlogo also. At the end of /var/log/Xorg.log.old I see:

…

[ 11088.573] (II) UnloadModule: “libinput”
[ 11088.739] (II) Server terminated successfully (0). Closing log file.

I investigated the settings of these utilities in /etc/X11/app-defaults and found, if I disable (add ! at the begin of the line) the setting:

XLogo*iconPixmap: xlogo32 <- in /etc/X11/app-defaults/XLogo

XCalc.IconPixmap: calculator <- in /etc/X11/app-defaults/XCalc

Then the trouble has gone – both utilities start and operate correctly.

About the hardware: the trouble met on my both laptops: Intel Atom N270 and Toshiba Libretto W105 – both use Driver “intel”: Atom by default, Toshiba – forced with conf file. Even if I remove the settings and Toshiba uses “modesetting” driver – the trouble stays on.

What’s wrong with Pixmap ? I’d tried launch XLogo via strace, and found:

I launched it so:
chvt 2
DISPLAY=:0 strace -yf xlogo >xlogo_fail 2>&1

But I can’t understand how exactly interpret all above. Like “I don’t see bitmaps, so I kill X server” – XLogo says ? Are you serious ?! Well, appeared:

$ LANG=C apt-cache policy xbitmaps
xbitmaps:
Installed: (none)
Candidate: 1.1.1-2

After the package had been installed, the trouble has gone. No need X be restarted. Let me point also: Atom has fresh installed Antix 19, Toshiba had been upgraded from 17. In /var/log/apt/history.log* there is no a mention of it.

Probably it’s not only intel card trouble, so xbitmaps should be included into AntiX base/full installation. It’s a small package.

Howdy and Welcome. I would stepped in using dmesg in terminal with grep and name of app to see what is up.

Thanks ! I always miss some source of information to check. Interesting things has been found in dmesg:

[11088.399773] jwm[10520]: segfault at 4 ip 00505567 sp bfe199b8 error 4 in jwm[4f3000+28000]
[11108.588661] elogind-daemon[1886]: Removed session 1.

Timestamps are the same as those in Xorg.log.0.old, so most probably jwm itself is the source of the trouble:

[ 11088.573] (II) UnloadModule: “libinput”
[ 11088.739] (II) Server terminated successfully (0). Closing log file.

Therefore X shows the usual closing messages, not errors – as it happened after jwm had died.

Thanks for helping figure it out !

Just figured I’d mention. When I am lazy and don’t feel like looking up command line synatax for finding why some apps crash.

I just poke and hope with changing gtk themes using antix control center > Desktop > Custom Look and Feel

Play with the settings in there and see if crash goes away. Make a note of which theme is the cause if it is the cause.

I’d check if it’s JWM trouble first. And switched to fluxbox. No problem with xlogo there. Then I switched back to JWM and tested different Widgets and Icon Themes, even Mouse Cursor. Also enabled “accessibility in GTK+ applications” under Other tab. No difference: if no xbitmaps package installed then total logoff appeared with any combination of settings. I suppose lxappearance settings are independent of chosen WM, so it proves JWM is the source of the trouble, no ?

Am I right, you don’t meet the crash under JWM when start xlogo/xcalc ? So is it just me ?

On my box:

jwm crashes when xlogo is typed into a terminal. No crash with other window managers.
Once xbitmaps is installed, no crash.

Conclusion: Install xbitmaps and all window managers plus xlogo work ok.

Thank you, anticapitalista ! One uncertainty less. It’s up to you how to apply the fix. It seems not much people use JWM.

I’d bet that more people use jwm than run xlogo 🙂

Yes, but xcalc is much more useful. And it got the trouble too. In your case also ? I tested xlogo mostly as it is more simple.

Yes, same issue with xcalc and jwm without xbitmaps.

But, since antiX base and full ship with galculator, I doubt xcalc is used much either.

New builds of antiX (gui) ie antiX-19.3 will ship with xbitmaps so many thanks for your post highlighting this bug for users that want to run xapps like xcalc/xlogo on jwm.
