OpenGL problem
- Anmelden oder Registrieren um Kommentare zu schreiben
Hi,
I'm trying to run an OpenGL program from a tutorial and I get the following errors:
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 153 (GLX)
Minor opcode of failed request: 34 ()
Serial number of failed request: 36
Current serial number in output stream: 35
Any ideas?
Thanks
Running mini? Try this
sudo apt-get install libgl1-mesa-dri
Of course if you are still on Trisquel 6, this is better:
sudo apt-get install libgl1-mesa-dri-lts-trusty
@lembas I'm not running mini. I installed 'libgl1-mesa-dri-lts-trusty' but still the same problem.
You may need this: [1]
sudo apt-get -s install --install-recommends linux-generic-lts-trusty linux-image-generic-lts-trusty \
linux-headers-generic-lts-trusty xserver-xorg-lts-trusty libgl1-mesa-glx-lts-trusty
If everything is ok --if and only if-- remove '-s' (stands for simulation).
Before reboot!!!, references must be updated:
sudo dpkg-reconfigure xserver-xorg-lts-trusty

I didn't notice any errors with -s so I removed it and ran again the command with reconfigure after that, but after reboot the gui disappeared so I had to install some packages again to bring it back. Also this message appeared:
Your Current Hardware Enablement Stack (HME) is no loner supported since 2014-08-07. Security updates for critical parts (kernel and graphics stack) of your system are no longer available.
For more information, please see:
http://wiki.ubuntu.com/1204_HME_EOL
There is a graphics stack installed in this systems. An upgrade to a supported (or longer supported) configuration will become available on 2014-07-16 and can be invoked by running 'update-manager' in the Dash.
So now I am again in the same situation as before. Thanks anyway.
