Comments on After update, OpenGL does not work until reboot

After update, OpenGL does not work until reboot

+1
−0

Whenever I do a big system update, OpenGL stops working until the next reboot. This also prevent OpenGL apps from launching. Example:

$ glxgears 
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  151 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Value in failed request:  0x0
  Serial number of failed request:  28
  Current serial number in output stream:  29

This goes away when I reboot. How can I make it go away without rebooting?

Can you pinpoint exactly what you updated? You might (might) be able to rmmod and then modprobe the relevant kernel module, but the details will depend on exactly what needs to be done.

Hmm. I assumed there was just a single obvious program that is the culprit. This was a big pacman update, so it's hard to say exactly why it was. I can keep an eye on it in future updates. What exactly would I do with rmmod/modprobe? Are there any useful keywords to look for in the pacman log?

No, not really, they are just the commands that load (modprobe) and unload (rmmod or, actually, these days modprobe -r instead) modules ("drivers" in the Windows world) from the kernel. What you describe is often caused by a new module that needs to be reloaded although I haven't seen this in a while now since most are handled via DKMS.
