Depois de mexer com alguns PPAs na tentativa de atualizar os drivers do Mesa no Linux Mint 17.3 KDE no meu Lenovo Ideapad, consegui aparentemente trazer tudo de volta ao funcionamento. Agora, no entanto, sempre que tento executar um programa OpenGL, recebo uma saída assim:
$ glxgears
libGL error: pci id for fd 4: 8086:1916, driver (null)
i965_dri.so does not support the 0x1916 PCI ID.
libGL error: failed to create dri screen
libGL error: failed to load driver: i965
e ao desistir, algo assim (ou um segfault incomum, com meus próprios projetos relacionados a allegro):
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
after 13936 requests (13934 known processed) with 0 events remaining.
enquanto o programa, aparentemente, é executado normalmente. (Exceto que o glxgears não parece estar se limitando a 60fps, o que aconteceu antes).
Veja uma saída esperançosamente relevante:
$ lspci | grep VGA

EDIT: lspci -v revela que o "driver do kernel em uso" é "i915_bpo". Isso deveria ser o i965?

EDIT: Praticamente todos os aplicativos relacionados ao GL têm se comportado mal de alguma forma ou de outra; GIMP, especialmente. Estes definitivamente não são os drivers que eu tive anteriormente. O ppa-purge também foi inútil, embora eu tenha excluído manualmente os arquivos ppa.
