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 ---

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); ```auto /sbin/lspci -nnk | grep -A2 VGA xrandr ``` – Cheers Malcolm °¿° LFCS, SUSE Knowledge Partner (Linux Counter #276890) SUSE Linux Enterprise Desktop 12 GNOME 3.10.1 Kernel 3.12.44-52.10-default If you find this post helpful and are logged into the web interface, please show your appreciation and click on the star below… Thanks! ---

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 ```auto /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 ```auto xrandr ``` is ```auto 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) 338mm x 270mm 1280x1024 60.0*+ 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 VIRTUAL1 disconnected (normal left inverted right x axis y axis) ``` Thank you, Flo ---

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 ```auto 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: ```auto 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 ---

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. – Cheers Malcolm °¿° LFCS, SUSE Knowledge Partner (Linux Counter #276890) SUSE Linux Enterprise Desktop 12 | GNOME 3.10.1 | 3.12.44-52.10-default If you find this post helpful and are logged into the web interface, please show your appreciation and click on the star below… Thanks! ---

Hi, sorry my English is not very advanced. what means: > [@](#): > > you would be best to raise an SR that UEFI booting is causing an issue I think I use (U)EFI boot mechanism, and the 1024 x 768 (4:3) resolution. Thank you, Flo
