Description Q4OS Team 2016-09-23 04:12:59 CDT

OpenGL TCM module doesn't start. Tested on real hardware as well as in Virtualbox. Exact steps to reproduce:

- Fresh TDE stable (14.0.3) installation on Debian Jessie.
- Run in term: 'tdecmshell opengl'
- No window, even a messagebox opens, the process gets stuck.

Please, you can test it with R14.0.4~preliminary?

Comment 2 Q4OS Team 2016-09-27 02:31:19 CDT

Virtualbox 64bit
Debian Stretch
TDE: R14.0.4 [DEVELOPMENT]

The same issue

Comment 3 Michele Calgaro 2016-09-28 08:16:48 CDT

Q4OS, can you try using R14.1.x? I can not reproduce on debian/stretch + TDE R14.1

Comment 4 Q4OS Team 2016-11-10 04:10:22 CST

The issue still persists in Debian Jessie, TDE 14.0.4 stable.

Comment 5 Michele Calgaro 2018-04-23 09:04:16 CDT

Just tried this in buster using R14.1 under VM.
When I run tdecmshell opengl from terminal, I get some error messages like below and no window at all. 
@Q4OS team: is this what you also see?

Sample of error:
X Error: BadValue (integer parameter out of range for operation) 2
  Major opcode:  154
  Minor opcode:  3
  Resource id:  0x0

"is this what you also see?"
Yes, it is

Comment 7 Michele Calgaro 2018-04-24 01:47:04 CDT

thanks Q4OS team.

Comment 8 Michele Calgaro 2018-04-26 01:55:21 CDT

As further info, I noticed this when running in VirtualBox.

If 3D hardware acceleration is enabled in VBox settings, the following error message is displayed in the CLI when running 'tdecmshell opengl'
"OpenGL Warning: vboxCall failed with VBox status code VERR_BUFFER_OVERFLOW"
and the tdm window opens.

If 3D hardware acceleration is disabled in VBox settings, the error message described in comment 5 is displayed in the CLI when running 'tdecmshell opengl'
and no window gets opens, although the process does not exit to CLI.

Comment 9 Michele Calgaro 2018-04-26 09:20:02 CDT

R14.1 commit: b5741b36
R14.0 commit: be0069e3

This should now be fixed. Could you please test and let me know before I close the bug. Thanks

Comment 10 Q4OS Team 2018-04-27 01:55:04 CDT

I can confirm, the module now opens. I have noticed another small glitch, as there is two identical "Direct Rendering" entries below each other in the list. Except this glitch, the module works fine, thanks for all your work.

Comment 11 Michele Calgaro 2018-04-28 07:50:55 CDT

Commits 19d18dfe (R14.1) and 3b0afd6c (R14.0) remove the double entry of "Direct Rendering".
I should have noticed in first place, sorry for that.

Please check again and let me know if it is ok to close the bug.

Comment 12 Q4OS Team 2018-05-01 16:37:31 CDT

Works fine now, thanks
