upgrade to leap to 15.0 does not work in graphic mode

I have a I7 PC booting in dual mode Linux / win-10 using grub2.
I used to run for several years leap 42.1,42.2 & 42.3 with KDE in dual more without any problems.

I wanted to update my OpenSuse to leap 15.0 and for that I flashed a memory stick with the leap 15.0 image file, using Etcher program under won-10 as indicated by OpenSuse site.

Flashing worked perfectly, I booted from USB (change of boot sequence was required in BIOS) and the update started.
Everything worked perfectly, all packages were updated and just before the end an error message popped up saying “invalid merge argument grub2-efi for grub2”. There was a proposition for experts to open a debugger & file a problem, but I just discarded it since I am not an expert and continued.

Now the system boots, but does not reaches the graphic mode. The screen enters graphic mode but hangs showing a white square moving up and down into a triangle like shape without reaching logon screen.

ALT-F1 shows the msg “kvm disabled by bios”, but login prompt is there somewhat later and one ca login as user or root. Utilities e.g. mc work properly. The same is true for ALt-F2->ALT-F6 and ALT-F7 brings back the hanging graphic screen. /var/log/messages seem to show a failure of X services. My graphic card is an NVIDIA GeForce GT520 that worked perfectly before for all OpenSuse distribution including Leap 42.1->42.3

Can anyone help or suggest some idea…? Thanks SH.

Share with us /var/log/Xorg.0.log, either via susepaste command or via http://susepaste.org. I suspect as many NVidia users do that you installed the proprietary driver in 42.3, which is useless in 15.0, and is not upgraded via the 15.0 installation media. Xorg.0.log should tell us if that is the case. If it is, either you must eradicate the proprietary driver and all its components so that one of the FOSS drivers can be used, or you must upgrade the proprietary driver to a version made for 15.0.

Thanks for your support ! I used indeed the information from this link http://opensuse-guide.org/3d.php related to NVIDIA graphic cards.
I can get as far as character mode, and the file you ask (/var/log/Xorg.0.log) is a pretty large file.
I will try to send it using the method you indicated, but given that no browser works in character mode, how can I send you the file, can you give further indications? Thanks SH.

If necessary, do (as root or using sudo):

zypper in susepaste

first, then,

man susepaste

for instructions. Likely

susepaste -n sharphawk -e 40320 /var/log/Xorg.0.log

will do it.

Since you know you installed the proprietary driver in 42.3, uploading that file is probably superfluous, and you’ll be needing to find the instructions for how to remove the existing version, or to upgrade to a version applicable to 15.0 that uses the cmdline instead of 1-click.

Thanks for you information, patience and support.
Allow me to point out to you that I upgraded NVIDIA drivers using OpenSuse information for leap 15.0 as indicating in the link http://opensuse-guide.org/3d.php for NVIDIA cards and in my previous post.
I will try to follow your indications. thanks, friendly yours SH.

I did precisely what you suggested. The utility “susepaste” was installed already as zypper nicely notified.

The suggested command "susepaste -n sharphawk -e 40320 /var/log/Xorg.0.log " gave the following answers:

Pasted as:
http://susepaste.org/66472894
http://paste.opensuse.org/66472894

Error: Can’t open display: (null)
Link is also in your clipboard.

It sounds to me that things worked, the last messages might be of little importance.

A last information: in graphic mode the screen hangs for minutes (about 5?) showing white square moving up/down into a white triangle. After this long while, suddenly “leap” is displayed in green at the bottom of the screen and the screen gets switched to login prompt in character mode. Only at that moment (i.e. rather late) ALT-F1–>ALT-F6 allow for logging in in character mode and ALT-F7 shows a black screen.

Thanks again, hopes this helps, expecting your feedback, friendly yours SH.

PS. Please see my comments in previous posts about NVIDIA drivers updates using openSuse indications for leap 15.0 in link: http://opensuse-guide.org/3d.php . Maybe an documentation update is required there.

Hello,

I did as indicated in OpenSuse documentation for leap 15.0 and NVIDIA drivers.

In character mode, as root, I executed the commend:
"zypper se x11-video-nvidiaG0* " and got as answer x11-video-nvidiaG03 and x11-video-nvidiaG04.

Since my video card is a GeForce GT520 I choose to go for x11-video-nvidiaG04.

As a next, as root, I entered the command:
“zypper in x11-video-nvidiaG04” the answer was the request to install about 8 packages, I said yes and it installed all of them with a long delay while installing the nvidia driver.
Precisely I used mostly information from this page: https://en.opensuse.org/SDB:NVIDIA_drivers.

After reboot graphics seem to work much better. This text is types under Linux graphics from Firefox:). I need to do several other tests, but it seems it works much better.
A last question: in Yast there is active a repository https://download.nvidia.com/opensuse/leap/15.0. What to do with it? Shall I disable it, delete it or keep it: please advise.
Thanks anyhow for your support, patience and advice, friendly yours SH.

Leave the Nvidia repo active. In case of a new kernel update the corresponding nvidia kernel modules ( drivers if you want ) need to match the new kernel, so updated packages will arrive in that repo. If you disable it, you defnitely will run into trouble one of these days.

I did as you recommended, the NVIDIA repository is left enabled: THANKS!! Friendly yours SH.
