Fglrx AMD Driver troubleshooting on ubuntu-gnome 15.04
I install fgrlx driver on vivid os the driver look like is istalled correct on system and built the necessary kernel modules because the dpkg log not report any errors, i configured the driver by simple commands like:
sudo aticonfig --initial sudo aticonfig --screen-layout=on i reboot the machine , but i face an strange issue the boot splash screen is hangup,i cant enter my lvm password to boot the system, i was have a chance to boot into rescue mode when boot to rescue mode the display not read by the system i try to export display by export DISPLAY=:0 I try to configure /etc/X11/xorg.conf there is not good resaults the boot splash still hang up I edited the grub , i uncomment "quiet splash" modified by "nomodeset" i can boot without boot splash but im faced other issue i cant switch to virtual tty i dont know is this a bug in the driver or in the kernel any suggest |
You need modesetting for a tty/X swap to work.
I would comment out "quiet splash" and "nomodeset", as the more information available, the quicker problems get solved. To help people help you, Post the output of Code:
lspci |grep VGA |
Thanks to offer some help for me here i post the output of:
# lspci |grep -i VGA 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450 / R5 230 OEM] |
Did you try this?
Code:
I would comment out "quiet splash" and "nomodeset", |
Yes i tryed to comment out "quiet splash" and "nomodeset" and leave this option in grub is empty like this ""
But there is not work |

It boot without quiet splash , i founded the drive fglrx is installed and working on system but there no virtual tty you can switch to using alt+ctrl+f1 its blank screen i tryed to configure my xorg by many ways but there is no good resaults
|
As a quick fix, edit /etc/inittab. There is a section something like this:
Code:
# These are the default runlevels in Slackware: |
Ubuntu version 15 is not support inittab any more its support runlevels par example single user mode , multi user mode , rescue mode ,graphical mode , the default is graphical user mode when i change to multiuser mode this prevent gdm from loading i try to reset the systemd-logind but this is not work .
|
Using console runlevel was the advice, whatever way Ubuntu implement it. X is started using something else - xdm? never bothered with it. Here I just seem to have Xorg running, and a window manager
|
Why not boot from your live media mount your root, chroot in and uninstall fglrx?
|
The probleme is not how to uninstall fglrx the probleme how i can make the virtual tty work after installation but after work on vivid version 15.04 there is a big probleme with fglrx graphic drivers should fix there is some thing i want to post when you run last command
#last OUTPUT DISPLAY UNKNOWN SCREEN (unknown :0 :0 Thu May 14 19:09 - 19:10 (00:00) i try to solve to add screen but without any good resaults ( i face this before on kali linux) now its on vivid too |

Actually there is a reason to use fglrx....
I have an HP Elitebook 8460p with Ubuntu 15.04. It has the radeon 6400m/7400m graphics card.
The reason I installed fglrx was to have control of the overscan and underscan properties which are not available with the default radeon driver - as far as I could tell. When I connect the laptop to a Seiki TV with HDMI and 1080p, the visible area is slightly larger than the monitor. With the AMD control center I can control the overscan and get the screen size to match the monitor. And yes, I also have the problem where the virtual terminals are black. I verified they are *functional* by logging into one and doing a 'wall' command so the issue appears to be that the foreground and background color of the framebuffer are both black. |
