I am currently having massive trouble with the configuration of the graphics on a friends laptop.
The specs are as follows:
Laptop: Toshiba Satellite L850-1L1
GPU: AMD Radeon HD 7670M @ 2GB DDR3 VRAM
internal display Resolution: 1366 x 768
Linux System: OS 12.3 64bit Install, KDE desktop, UEFI boot using GRUB2-EFI
Windows system: Windows 8
Category: Screen distortion/displacement
drivers: radeon, fglrx
I first ran into a problem when trying to install OS 12.3 parallel to the preinstalled W8.
At that time the bootloader refused an installation yielding an error saying sth. That “mkinitrd” failed and listing “radeon”. That was when I tried to install after switching from UEFI to CMS (trying to avoid any modiication to the existing W8 install, lest I damage it).
Then I tried an installation with(!) UEFI enabled but forced text-mode installation for good measure(?). That worked all right.
Problems started after the installation and configuration was complete. The system booted into a screen as in the following picture:

I then rebooted into failsafe mode and instaled the proprietary AMD driver. After running
and a reboot I got an output similar to this:

fiddling with aticonfig, hsync, vsync settings and Catalyst Control Center did not bring any changes, so I uninstalled fglrx in failsafemode usingCode:aticonfig –uninstall
Then got the same problem back as before.
After a few more installs/uninstalls of FGLRX (script-install, generating a system specific package then installing it) and looking in the forums I found the proposition of appending “radeon.modeset=1” to the boot commands. That seemed to work when using the “radeon” driver.
As the system was simply alive, not allowing any changes to screen resolution I decided to try FGLRX again (yeah – ignoring the saying “never touch a running system”)
That went horribly wrong. Installing FGLRX as described in SDB (from the listed repos) (all with multiple reboots and blacklisting of “radeon”) didn't help the problem, still the warped and striped screen. Same holds for “radeon” though the problem there shifted to the warped and striped screen instead of simply an out-top screen.
Note here: the “radeon.modeset=1” option did not help me again but “nomodeset” left the system at the message “Starting graphical interface” where the X-Server dies (be it fglrx or radeon driver).
I have tried the suggestions written in:
I have tried these suggestions for both drivers. The xorg.conf file used with fglrx is
Code:Section "ServerLayout" Identifier "aticonfig Layout" Screen 0 "aticonfig-Screen-0" 0 0 EndSection Section "Module" # Disable "dri" # Disable "dri2" EndSection Section "Monitor" Identifier "aticonfig-Monitor-0" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" # Option "DPMS" "true" Modeline "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsync # Modeline "1368x768_76.00" 111.00 1368 1448 1592 1816 768 771 781 805 -hsync +vsync EndSection Section "Device" Identifier "aticonfig-Device-0" Driver "fglrx" Option "Capabilities" "0x00000800" Option "Centermode" "off" Option "UseFastTLS" "off" # Driver "radeon" BusID "PCI:1:0:0" EndSection Section "Screen" Identifier "aticonfig-Screen-0" Device "aticonfig-Device-0" Monitor "aticonfig-Monitor-0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1368x768" EndSubSection EndSection
The best results were achieved with this – once two consecutive reboots with a normal screen.
As the tips in the above threads were made for the radeon driver I have tried them with it, putting the settings into /etc/X11/xorg.conf.d/50-device.conf and 50-monitor.conf, that did not do any good – only two startups with shifted screen, then back to the out-top one.
I also tried the configuration from ArchWiki, but it did not help.
Currently the laptop is running with “x11failsafe” boot option, to allow at least some work but this problem seriously annoys me.
The Xorg.0.log.old are for different startups. The first one is a startup with fglrx, the next one is with radeon into normal mode and then radeon and failsafe mode :
Does anybody have any idea how one could tackle it? I would appreciate it very much, as I have spent 12+h on this, any driver would be fine, as long as it at least works)
