Could you please switch to radeon card, install catalyst, then remove files as root
sudo rm /var/log/dmesg* && sudo rm /var/log/Xorg*
THEN, immediately reboot, switch in BIOS to Intel, let system boot and hang.
THEN, switch back to radeon, boot up, and attach those files to your post, for example as archive (zip,7z,gz etc)
This way, you will attach relevant logs in the moment of crash. Because currently, there are no logs. No logs - no real help.
They are in "/var/log/.." and are text files/archives.
Dmesg-command is a binary in "/bin/dmesg", on contrast. Do not confuse.
I remember that if you use Fedora, there is systemd and now there should be different way/location. You can ask Google or IRC of Fedora how to capture your kernel and Xorg logs.
Thats basically what step above did - clean them, do steps leading to the problem, and then submit the logs with crash info.
It looks like it's /var/log/messages* files in Fedora.
Hi, Here is what I would do in your case :
Create 2 separate boot options, one for intel graphics and one for AMD, both of these entries have a different (random) command line parameter. in this case, let's assume intel and catalyst.
the kernel command line can be accessed through /proc/cmdline.
Now prepare two xorg.conf files. name one xorg.conf.intel, the other xorg.conf.catalyst. As their names imply, one should work when you want the intel card, the other with the AMD card.
now the fun part. to switch at runtime, we must create a script. something along the lines ofput this script somewhere in your system. Now we must create a systemd unit file for it :Code:#!/bin/bash if [ "$1" = "start" ];then grep -o catalyst /proc/cmdline && cp /etc/X11/xorg.conf.catalyst /etc/xorg.conf grep -o intel /proc/cmdline && cp /etc/X11/xorg.conf.intel /etc/xorg.conf fi if [ "$1" = "stop" ];then rm /etc/X11/xorg.conf fiput this unit file into /etc/systemd/system named as xorg-switch.service. enable it using sytemctl enable xorg-switch.serviceCode:[Unit] Description=switch xorg.conf [Service] Type=oneshot ExecStart=/path/to/script/script.name.sh start ExecStop=/path/to/script/script.name.sh stop [Install] WantedBy=multi-user.target
note that this approach isn't very safe, nor is this a copy & paste guide. This is more of a braindump of how I would go about your issue which, from what I gather, is mostly changing the X configuration depending on the BIOS setting. If not, please be more specific.
According to logs:
And then fglrx proceeds seeking device, finds none and Xorg aborts with screens not found.Code:[ 6.184] (==) Log file: "/var/log/Xorg.0.log", Time: Sun Apr 28 15:22:13 2013 [ 6.184] (==) Using config file: "/etc/X11/xorg.conf" [ 6.184] (==) Using config directory: "/etc/X11/xorg.conf.d" [ 6.184] (==) Using system config directory "/usr/share/X11/xorg.conf.d" [ 6.184] (==) ServerLayout "aticonfig Layout" [ 6.184] (**) |-->Screen "aticonfig-Screen-0" (0) [ 6.184] (**) | |-->Monitor "aticonfig-Monitor-0" [ 6.184] (**) | |-->Device "aticonfig-Device-0"
My understanding is that fglrx has installed own static "xorg.conf.d" Xorg session config in
and it disables autoprobing for intel driver. Given that the radeon card is disabled and only fglrx session is laid out, after fglrx aborts, Xorg is left without screens.
When you use radeon driver+intel, they rely on Xorg automatic configuration. Unlike fglrx, they don't need static config.
What you need, if I am correct, granted you want to keep fglrx, is to have two video card static configuration (session layouts). One for intel driver (which needs to be created), another for fglrx.
So that, after fglrx finds no adapters, Xorg proceeds loading Intel driver, which should return a screen.
The good news is that its just plain configuration files issue, nothing messed in your system.
The bad news, is that I have never had configuration with multiple video cards in the system, configured via xorg.conf.d way.
The best way would be to open a bug by fedora bugtracker.
Open a bug containing words "Intel + fglrx, IBM T500, muxed" and attach all logs there.
Would be also nice, if you archive and attach all files from /usr/share/X11/xorg.conf.d/
Copy the full problem description you filled under your linked post in first thread.
Then they will be able hopefully to give you direct instructions/configs to copy into your system.
The majority of solutions for your T500 laptop on internet configure BIOS VGA to discrete, then use either radeon or fglrx.<
