Errores gdm/kdm y gnome

[joseangelmadrid]

Sigo con los problemas de arranque con gnome.
Después de haber instalado KDE me ocurre lo siguiente.
Sea cual sea el gestor de arranque que use, KDM o GDM, Gnome no arranca
a la primera. La barra o panel de Gnome aparece y desaparece y no puedo
arrancar. Me voy a consola y hago un 'sudo killall gdm' o 'sudo killall
kdm' y después 'sudo kdm' o 'sudo gdm' para rearrancar. Entonces, si
elijo trabajar con KDE funcionan todas las aplicaciones. Si elijo
trabajar con Gnome {tras el 'killall' esta segunda vez sí se me carga el
panel} sólo funcionan las aplicaciones estrictamente KDE {ninguna
aplicación gnome funciona, ni tampoco Firefox, ni Thunderbird...}. Las
ventanas hacen el amago de aparecer, pero mueren antes de haber podido
interactuar con ellas.
Sin embargo, si elijo trabajar con KDE, todo funciona a la perfección,
sea KDE o sea Gnome.

Pego aquí el archivo .xsession-errors a ver si alguien me dice qué está
pasando:
