GUI Problem after Installation

SUSE Linux Enterprise Server SLES Install-Boot
1

Hello Forum Users,

I have a Problem with my SLES 12 installation, with a Gnome GUI.

I have installed the system the second time, but my error not disappear. By starting my System I can’t use the taskbar with her whole functions.

The applications Icon and the „restart, shutdown“ Icon I cannot use.

If I press the keys: Strg + Alt + Backspace and log in again it’s work.

My Installation DVD has no errors. It’s a possibility that there is a hardware error?

What can I do?

Thank you for reading,
Flo

Hi, Sorry: some more infos,

I want to use my system by default with the console and just for extension the GUI.

So I can start the console, but how can I repair the GUI?

Thank you,
Flo

Hi
It could be related to the graphics card in your system. Is this set to
autologin to the GUI?

Can you post the output from the following two commands (post the
output in code tags the <#> button);

/sbin/lspci -nnk | grep -A2 VGA
xrandr

Hello and thank you,

Do you mean that the system goes autologin without password? No it isn’t set so. I must type a password.

the output of

/sbin/lspci -nnk | grep -A2 VGA

is

00:02.0 VGA compatible controller [0300]; Intel Corporation Xeon E3-1200 v3 Processor Integrated Graphics Controller [8086:041a] (rev 06) Subsystem: Fujitsu Technology Solutions Device [1734:11f4] Kernel driver in use: i915

and

the ouput of

xrandr

is

Screen 0: minimum 8 x 8, current 1280 x 1024, maximum 32767 x 32767
VGA1 connected primary 1280x1024+0+0 (normal left inverted right x axis y axis)

Hi
That all looks ok. Have you done any other tweaks in the Gnome-shell GUI (changed fonts etc), or all at defaults?

If you have done some tweaking, create a test user and login, is the issue duplicated?

It may also be the intel uxa/sna issue. This can be checked by adding the following file in /etc/X11/xorg.conf.d

vi /etc/X11/xorg.conf.d/20-intel.conf

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "uxa"
EndSection

or for tearfree and sna;

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "sna"
   Option      "TearFree"    "true"
EndSection

Try them both and see if it helps.

Hello malcolmlewis,

I add a User but it’s not working,

and the two different entries in /etc/X11/xorg.conf.d/20-intel.conf

not working too. The System starts no GUI with this entries. And if I type startx I get
error messages.

A test without this files, and my GUI starts again, but with the conventional error.

But before console login I get following error messages:

EFI: Problem loading in-kernel X.509 certificate (-129)
EFI: Problem loading in-kernel X.509 certificate (-74)
Couldn't get size: 0x800000000000000e

Thank you,
Flo

Hello malcolmlewis,

I have interesting news.

I installed the system two more times.

First with (U)EFI. Then the first start after the installation the error was away.
The first restart the error comes again.

Then I installed it without (U)EFI, and the System works without error about 4 restarts.

The error appears since I installed with (U)EFI.

I don’t know what that means?

Thank you,
Flo

Hi malcolmlewis,

Sorry, its likelier not just a (U)EFI Problem but a secure boot Problem.

Thank you,
Flo

Sorry I do much mistakes,

it’s definitely a (U)EFI mistake.

Thank you

Hi
I run UEFI booting without issues, now one thing to look at is the
system BIOS up to date?

But if working fine via Legacy boot then I would stick to that, else
you would be best to raise an SR that UEFI booting is causing an issue.

Hello,

more Infos:

If I switch the resolution from:

1280 x 1024 (5:4)

to

1024 x 768 (4:3) or to 800 x 600 (4:3)

it’s work fine.

Hi,

sorry my English is not very advanced.

what means:

I think I use (U)EFI boot mechanism, and the 1024 x 768 (4:3) resolution.

Thank you,
Flo
