Hi David,
in your 1st post you said, that sometimes your login screen appears - are you able to logon to your laptop then?

if you're able to login,then post here output of following commands:

CODE

lspci
cat /proc/cpuinfo | grep model
dmidecode -t 0
dmidecode -t 1
dmidecode -t 4
lsmod | grep fglrx
lsmod | grep amd
lsmod | grep radeon
lshw -c display
uname -a


also check if you have file present:
CODE

ls -al /etc/X11/xorg.conf

if it is present - post here it't contents too ..

we'll determine which CPU/APU/VGA you use, which kernel, which VGA driver and then we'll see.

cheers

Hi David,

boot CD helps, but wont tell us everything - eg. won't tell us what VGA driver you really have installed on your laptop OS ...

QUOTE

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
and
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M] (rev ff)


Anyway - from the output we can see that you have (as i undertand it) 2 VGA on your laptop - so you need to install VGA driver that is capable of VGA switching.
From your first post, where you stated, that you get sometimes GUI and sometimes you don't this seams to me like the laptop is maybe using the 2 VGAs randomly.

What i would do 1st is, i would try to install AMD proprietary VGA driver and see if it solves the issue.

you need to setup elrepo repository and then install "kmod-fglrx" package.

1. goto:
Elrepo website and follow instructions there to install elrepo repository

2. issue:
yum --enablerepo=* install kmod-fglrx


If you cant get your GUI and you're not able to login on your laptop to achieve above, you can do it all from CLI without gui.
you could try:
1. try to use CTRL+ALT+F keys (F1 F2 F3 ...) try them all and see if you can get prompt - if you can, log as a root and install elrepo repository:
CODE

for SL 7
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm
for SL 6
rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm

and then:
CODE

yum --enablerepo=* install kmod-fglrx



2. i suppose you have SL 7 on your laptop (you certainly used SL 7 boot CD)

you need to set runlevel - now called on SL 7 boot target so that your system will boot without GUI
CODE

1.find your default target
systemctl get-default

2. set your target to below target (multitarget is without X or GUI)
systemctl set-default multi-user.target

3 reboot
shutdown -r now


and continue with elrepo install as described above
if you want to know more about different systemD targets - read eg. here
rhel 7 systemD targets (runlevels)

NOTE
if you really cant access your laptop and login in any way, you might need to enter 'rescue mode' and then issue the above command

To enter rescue mode you need to restart your laptop and then (i took this from rhel 7 manual) located here:
sl7 rhel7 rescue mode
QUOTE

Booting to Rescue Mode
Rescue mode provides a convenient single-user environment and allows you to repair your system in situations when it is unable to complete a normal booting process. In rescue mode, the system attempts to mount all local file systems and start some important system services, but it does not activate network interfaces or allow more users to be logged into the system at the same time. In Red Hat Enterprise Linux 7, rescue mode is equivalent to single user mode and requires the root password.

    To enter rescue mode during boot, on the GRUB 2 boot screen, press the e key for edit.
    Add the following parameter at the end of the linux line on 64-Bit IBM Power Series, the linux16 line on x86-64 BIOS-based systems, or the linuxefi line on UEFI systems:

    systemd.unit=rescue.target

    Press Ctrl+a and Ctrl+e to jump to the start and end of the line, respectively. On some systems, Home and End might also work.
    Note that equivalent parameters, 1, s, and single, can be passed to the kernel as well.
    Press Ctrl+x to boot the system with the parameter.


it was long read of the outputs and long post and i worked hard last week so it took me to a weekend to post reply ..

Hi helikaon,

I had to read several times your post to understand, but I can't acess login, so I had to use the rescue mode and then run the commands. I believe that solved the problem for now,
It was almost 3 weeks with this problem, sorry if I gave you a lot of work you really helped me.
I'm still learning but I hope soon to help others as well, thank you so much guys. http://th166.photobucket.com/albums/u117/rdshear/Smiley%20Faces/th_smiley-face-thumbs-up.gif

Hi David,
good to hear you have fixed it smile.gif Btw. one of my friends, who is a long time experienced Unix admin says: 'windows is a friendly OS - and Linux is too, but difference is, Linux chooses its friends carefully' biggrin.gif
Linux community still needs new enthusiastic people - and frankly, anyone sticking it up with Linux now, is a winner.
Why? Windows 10 is a security disaster and will be even greater theft of personal information, than google is right now...

I have just one favour to ask - if you'd have time - could you be more specific/detailed and write here, what you did exactly to fix the problem?
I'm sure in future would find some other people your post very informative and helpful..

Thank you

cheers

Hi helikaon,

Yes of course I can. So first what I tried to do was enter in the rescue mode, I can't acess my GUI then I use CTRL + ALT+ F2 and log as root and install elrepo repository:

for SL 7(in my case)
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm

So when I run:

yum --enablerepo=* install kmod-fglrx

But can't install because it has a conflict with the package xorg-x11-glamor, so you can try to solve this in two ways:

1 - disable glamoregl by renaming or removing /usr/share/x11/xorg.conf.d/glamor.conf
2 - uninstall xorg-x11-glamor

Regardless of the option you choose I believe it will work, in my case I choose the number 2.

Then I run again:

yum --enablerepo=* install kmod-fglrx

"you need to set runlevel - now called on SL 7 boot target so that your system will boot without GUI"

1.find your default target
systemctl get-default

2. set your target to below target (multitarget is without X or GUI)
systemctl set-default multi-user.target

3 reboot
shutdown -r now

I don't know if I could explain or confuse , but it was exactly what I did. http://th166.photobucket.com/albums/u117/rdshear/Smiley%20Faces/th_smiley-face-thumbs-up.gif
