Мой компьютер несколько устало показывает окна :) Это настольный компьютер с встроенной картой Intel, но с дискретной картой Nvidia в слоте PCI. Карта Intel отключена в BIOS.

Кто-то предложил запустить glxgears, и я получил такую ​​ошибку ...

$ glxgears
Xlib:  extension "GLX" missing on display ":0".
Error: couldn't get an RGB, Double-buffered visual

Другая информация, которая может помочь, заключается в следующем

Я просто хочу чтобы узнать, нормально ли происходит сбой glxgears или есть какие-то проблемы с конфигурацией моего компьютера ..

Попробовал, чтобы ничего не произошло ..

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current

А потом попробовал это, и это произошло :)

$ sudo jockey-text -e xorg:nvidia_current

Sorry, installation of this driver failed.

Please have a look at the log file for details: /var/log/jockey.log
$ tail -20 /var/log/jockey.log
