ATI

Error in /var/log/messages: unable to acquire AGP, error "xf86_ENODEV", cannot init AGP
A generic solution from ATI: X Fails to Load on Systems with Linux Kernel Version 2.6.x
An exact solution that worked: AGP not detected on Intel 8285P and E7205 chipsets using kernels higher than 2.6.17
  • rmmod i82875p_edac
  • rmmod edac_mc
  • rmmod fglrx
  • rmmod intel-agp (or another appropriate module from /lib/modules/`uname -r`/kernel/drivers/char/agp)
  • rmmod agpgart
  • modprobe agpgart
  • modprobe intel-agp (or another appropriate module from /lib/modules/`uname -r`/kernel/drivers/char/agp)
  • modprobe fglrx
  • blacklist the modules e7xxx_edac and edac_mc; e.g., add the following two lines at the beginning of /etc/modprobe.d/blacklist:
blacklist i82875p_edac
blacklist edac_mc
