My output
I'm on Fedora 19 and I get these messages.
$ dmesg | less [ 0.898072] Linux agpgart interface v0.103 [ 0.898214] agpgart-intel 0000:00:00.0: Intel HD Graphics Chipset [ 0.898439] agpgart-intel 0000:00:00.0: detected gtt size: 2097152K total, 262144K mappable [ 0.899719] agpgart-intel 0000:00:00.0: detected 32768K stolen memory [ 0.899978] agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000
Potential solutions
I found this ArchLinux forum thread titled: "[SOLVED] drm_pci_agp_init ERROR Cannot initialize the agpgart module". The solutions discussed in the thread suggest either blacklisting that module or removing drm module.
excerpt
SOLVED: I finally found a way how to disable the driver by removing drm.ko.gz:
cd /lib/modules/<kernel version>/kernel/drivers/gpu/drm/ rm drm.ko.gz
Alternatively, I can prevent any modules from loading by adding blacklist parameter in the boot entries:
blacklist=module#1,module#2,module#n
Another solution is that I simply removed the nomodeset parameter from my boot entries:
title Arch linux /vmlinuz-linux initrd /initramfs-linux.img options cryptdevice=UUID=<UUID>:<dm_name> root=/dev/mapper/<dm_name> [del]nomodeset[/del]
What's agpgart?
The wikipedia page discusses what agpgart is in this topic titled: Graphics address remapping table.
