[Solved] xscreensaver/glx problems since recent Xorg-7.7-3d.tcz upgrade

[GNUser]

Since the recent Xorg-7.7-3d.tcz upgrade to version 20.3.0, my portable version of xscreensaver fails with this kind of error:

Code: [Select]

glmatrix: display ":0.0" does not support the GLX extension.
glknots: display ":0.0" does not support the GLX extension.
glmatrix: display ":0.0" does not support the GLX extension.
lockward: display ":0.0" does not support the GLX extension.
geodesic: display ":0.0" does not support the GLX extension.
glmatrix: display ":0.0" does not support the GLX extension.
Any ideas how to fix, short of reverting to Xorg-7.7-3d.tcz version 19.2.3?

Did you update libEGL, libGL and libGLESv2 at the same time?

[GNUser]

The system is fully updated, so I assume those extensions were updated at the same time.

Code: [Select]

bruno@x200:~$ cat /opt/tcemirror
http://repo.tinycorelinux.net/

bruno@x200:~$ tce-update
Checking for Easy Mode Operation... OK

Press Enter key to begin batch update of extensions in /sda3/tce
or enter any char to exit now:
Checking Tiny Core Applications in /mnt/sda3/tce/optional
Your system is up-to-date.
Press Enter key.

bruno@x200:~$ tce-status -i | grep 'lib.*GL'
libEGL
libGL
libGLESv2

I can confirm that on this fully-updated TCL11.1 x86_64 machine, the problem goes away if I go into tce/optional/ and replace newest Xorg-7.7-3d.tcz with previous version then reboot.

[GNUser]

Maybe the portable application has a built-in, older version of one or more of these libraries. I'll check.

Hi GNUser
You could try this to see if it reveals anything:

Code: [Select]

ldd /Path/To/xscreensaver

[Rich]

Hi GNUser
If you load  mesa-demos.tcz  does this run without errors:

Code: [Select]

glxinfo

[GNUser]

Hi, Rich. Thanks for the suggestions.

Code: [Select]

$ ldd /opt/bin/xscreensaver
/opt/bin/xscreensaver: error while loading shared libraries: /opt/bin/xscreensaver: ELF file ABI version invalid
$ tce-load -wi mesa-demos
...
$ glxinfo
name of display: :0.0
Error: couldn't find RGB GLX visual or fbconfig
The  ldd  error doesn't bother me because I get the same error with all other AppImages, including ones that are working perfectly.

The glxinfo is more concerning. I will see if the error goes away when I load the older version of Xorg-7.7-3d.

[GNUser]

Everything points to a problem with the new version of Xorg-7.7-3d.tcz.

If I change nothing except replace new version of said extension with old version then reboot, then  glxinfo  works fine:

Code: [Select]

$ glxinfo
name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.4
server glx extensions:
    GLX_ARB_create_context, GLX_ARB_create_context_no_error,
    GLX_ARB_create_context_profile, GLX_ARB_fbconfig_float,
    GLX_ARB_framebuffer_sRGB, GLX_ARB_multisample,
...

[Rich]

Hi GNUser
Looking at the dates in the  .info  files:

Code: [Select]

mesa-demos.tcz        2019/11/11 recompiled against mesa-19.2.3
Xorg-7.7-3d.tcz       2020/12/06 updated 19.2.3 -> 20.3.0I'm guessing  glxinfo  may have failed because  mesa-demos  depends on  Xorg-7.7-3d  which was compiled after  mesa-demos.

Check your Xorg.0.log for any 3d/drm errors.

[Juanito]

I tested the update for several days before posting - I just checked again and glxgears/glxinfo, vkcube/vulkaninfo, xscreensaver and others all work as expected.

Code: [Select]

$ glxinfo | grep 20.3
    Version: 20.3.0
OpenGL core profile version string: 4.5 (Core Profile) Mesa 20.3.0
OpenGL version string: 3.0 Mesa 20.3.0
OpenGL ES profile version string: OpenGL ES 3.1 Mesa 20.3.0

[GNUser]

curaga, Xorg.0.log does not seem to contain any related errors: https://pastebin.com/mmFyP7te

I'm stuck because system is supposedly fully updated using official repo, but I can't get past this:

Code: [Select]

bruno@x200:~$ glxinfo
name of display: :0.0
Error: couldn't find RGB GLX visual or fbconfig
Maybe it has something to do with my graphics hardware? Graphics is really not my forte. My machine is an X200 ThinkPad with integrated Intel graphics and Libreboot.

I'll revert to older Xorg-7.7-3d.tcz for now.

Hi GNUser

curaga, Xorg.0.log does not seem to contain any related errors: https://pastebin.com/mmFyP7te ...

Wouldn't this be suspect:

[GNUser]

Yes, that sure does seem suspect. Strangely, zstd.tcz is loaded, /usr/local/lib/dri/i965_dri.so exists, and /usr/local/lib/dri/swrast_dri.so also exists.

I'm going to fudge the .md5.txt files of all related extensions, to force them to be re-downloaded from official repo during "tce-update". Let's see if that fixes it.

Hi GNUser

... I'm going to fudge the .md5.txt files of all related extensions, to force them to be re-downloaded from official repo during "tce-update". Let's see if that fixes it.

This has always worked to update everything:

Code: [Select]

tce-audit builddb
tce-audit updatedeps
tce-audit fetchmissing
tce-updateThen click the  Exit  icon and select reboot.

By the way, if any of your extensions is missing its  .md5.txt  file, it won't get updated.
