[SOLVED]HALP Xserver round two

[Function]

When trying solving the "screen tearing" issue I'm in trouble.

I messed around with this:

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt-get update
sudo apt-get upgrade
sudo reboot

followed by this:

sudo apt-get install mesa-utils
sudo mkdir /etc/X11/xorg.conf.d/
echo -e ‘Section “Device” Identifier “Radeon” Driver “radeon” Option “TearFree” “on” EndSection’ | sudo tee /etc/X11/xorg.conf.d/20-amd.conf
sudo reboot

After the reboot Linux doesn't start anymore

I get the message:

Failed to start the X server (your graphical interface). It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem?

When I answer NO I get The Xserver is now disabled. Restart MDM when it is configured correctly >OK
Then a blackscreen with Linux mint 17.2 Rafaela t-imedia-S2185 tty1

What can i do, I'm a bit paniken overhere.....

Boot to the Recovery mode, where drop to the root prompt and run

Code: Select all

mount -o remount,rw /
cd  /etc/X11/xorg.conf.d
mv 20-amd.conf 20-amd.conf.faulty
sync
reboot

PS. Those drivers is not intended to use in Mint 17

When I type

Code: Select all

mount -o remount,rw /

"-o" is "minus (alphabet)o" ????

"enter"

I get

Code: Select all

mount:only root can do that

Is that right? And can it be followed by the next sentence?

Code: Select all

cd /etc/X11/xorg.conf.d

for 12.04.3 LTS and later
During boot press and hold the left Shift key or any other key. This will bring up the Grub2 menu from where we can select "Advanced options for Ubuntu".

Holding the Shift key or any other key doesn't work. What can i do wrong with this????

for 12.04.0 and later
During boot press and hold the left Shift key or any other key. This will bring up the Grub2 menu from where we can select "Advanced options for Ubuntu".

The same!!!!!!

[Function]

Using "esc" right after "bios boot" gives:


"GNU GRUB version 2.02`beta2-9ubuntu1,14
Minimal BASH-like line editing is supported. For the first word, TAB list possible command completions. Anywhere else TAB lists device or file completions.

grub> _"

Using "esc" right after "bios boot" gives:

Just select advanced options and there Recovery Mode.

[Function]

Just select advanced options and there Recovery Mode.

There are no options, only

"grub> _"

[kukamuumuka]

Boot using liveDVD or USB and mount your system partition and open /etc/X11/xorg.conf.d directory as an administrator and rename 20-amd.conf as 20-amd.conf.faulty

[Function]

By pressing "esc" very short after "bios boot"

Reached:

"GNU GRUB version 2.02`beta2-9ubuntu1.14"
(with the options:)
- *Linux mint 17.2 Cinnamon 64-bit
- Advanced options for Linux Mint 17.2 Cinnamon 64-bit
- System setup

I choose: "Advanced options for Linux Mint 17.2 Cinnamon 64-bit"

options:
- Linux Mint 17.2 Cinnamon 64 bit, with Linux 4.4.0-112-generic
- *Linux mint 17.2 Cinnamon 64 bit, with Linux 4.4.0-112-generic (recovery mode)

choose "recovery mode"

Recovery menu (filesystem state: read-only

options (short!)

(or type Control-D to continnue):

"Control-D" no effect.
My password gives:

"t-imedia-S2185 `# (cursor)"

type: mount -o rw,remount /

no effect just "t-imedia-S2185 `# (cursor)"

type: exit

Back to "Recovery Menu (filesystem state: read/write)

choose: "resume Resume normal boot"

gives:
"You are going to exit the recovery mode and continue the boot seqeunce. Please note that some graphic drivers require a full graphical boot and so will fail when resuming from recovery.
If that's the case, simply reboot from the login screen and then perform a standard boot.
<OK>

OK

Gives:
"Failed to start the X server (your graphival interface). It's likely that it is not set up correctly. Would you likento view the X server output to diagnose the problem"

[Function]

Yes yeah. It is working again!!!!!!!!!!!!!!

So much thanx. You are a true hero. Buy yourself a beer!!!!!

[Function]

Oh no, oh nonononononono,

It's back....with a vengeance.

In the topic "screen tearing" viewtopic.php?f=47&t=269727 that I have started to safely work on the issue "screen tearing", is the following suggested.

+1 on installing the closed driver (fglrx) from Driver Manager if you're on 17.2,

Menu -> Administration -> Driver Manager. It'll show the open source driver being installed and allow for install of "fglrx" and "fglrx-updates". As said, those are probably the same driver also on 17.2 but if not, pick the one with the higher version number.

So, first I allowed for install of "fglrx". That had no effect.
Then "fglrx updates". That had also no effect.
Then I tried a new start up.....

And there it was again:
"Failed to start the X server (your graphical interface). It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem?"

So, I tried in "Recovery" the above (further in this topic!) solution that worked before.

Code: Select all

mount -o rw,remount /
cd /etc/X11 xorg.conf.d
mv 20-amd.conf 20-amd.conf.faulty
sync
reboot

after

Code: Select all

mv 20-amd.conf 20-amd.conf.faulty

I get:

Code: Select all

mv: cannot stat '20-amd.conf': No such file or directory

Can somebody please help me with this?????????
