[Solved] Screen freezes few seconds after logging in.

Question

Hey there.
I'm looking for some guidance if possible.
I installed Arch in an external hard drive to test out the compatibility with my laptop (a LG P1-J331P > http://pastie.org/8548089 ) with an ATI Mobility Radeon X1400 video card. All following the beginner's guide [https://wiki.archlinux.org/index.php/Beginners%27_Guide] and relevant wiki for the external/usb device installation [https://wiki.archlinux.org/index.php/Usb_installation].
Running arch with "nomodeset" on kernel parameter, it runs normally, except that the screen resolution was fixed at [email protected], though it should be maxed at 1280x800@60.
When "nomodeset" is set:
$dmesg | grep radeon
[ 10.859500] [drm] VGACON disable radeon kernel modesetting.
[ 10.859507] [drm:radeon_init] *ERROR* No UMS support in radeon module!
Without using "nomodeset", the system detects correctly the screen resolution but it freezes few seconds later after logging. Can't Ctrl+Alt+F1.
Tried:
- added "radeon" to MODULES array in the mkinitcpio file. And run the subsequent "mkinitcpio -p linux";
- created a "/etc/rc.d/rc.local" file with contents:
modprobe -r radeon
modprobe -r drm
modprobe radeon modeset=1
- tested "radeon.pcie_gen2=0", "pci=nomsi", "noapic" and "acpi=off" to the kernel parameter.
- created a "/etc/X11/xorg.conf.d/10-monitor.conf" file with contents: http://pastie.org/private/bhcbfvs3zvplvspwamxa2q
Video card drivers installed: mesa, xf86-video-vesa and xf86-video-ati.

Any advice for this newbie would be appreciated.

Answer 1

- Tried creating a "/etc/X11/xorg.conf.d/20-radeon.conf" file with contents:
Section "Device"
Identifier "ATI Mobility Radeon X1400"
Driver "radeon"
Option "SWcursor" "off" #software cursor might be necessary on some rare occasions, hence set off by default
Option "EnablePageFlip" "on" #supported on all R/RV/RS4xx and older hardware, and set on by default
Option "AccelMethod" "EXA" #valid options are XAA, EXA and Glamor. EXA is the default
Option "RenderAccel" "on" #enabled by default on all radeon hardware
Option "ColorTiling" "on" #enabled by default on RV300 and later radeon cards
Option "EXAVSync" "off" #default is off, otherwise on. Only works if EXA activated
Option "EXAPixmaps" "on" #when on icreases 2D performance, but may also cause artifacts on some old cards. Only works if EXA activated
Option "AccelDFS" "on" #default is off, read the radeon manpage for more information
EndSection
    And the subsequent Xorg.0.log > http://pastie.org/private/goyhnu9bzxhzybl4sisaa
    With this file and using "nomodeset", the boot would be stuck at :
[ OK ] Reached target Graphical Interface.
    But without "nomodeset" parameter, it would successfully launch the graphical login but still freezes a few seconds after logging in.
