Clean install of 42.2 on an HP Proliant G7. Login screen is fine but after login video is unreadable (looks like numerous versions interlaced.) However, 42.1 installed on an identical machine has no such problem. Please advise.
Hi
What graphics cards are on the 42.1 and 42.2 systems?
/sbin/lspci -nnk |grep -A3 VGA
Also are you running a desktop environment, if so which one.
Not being able to do anything after login or yet to ssh in, I can’t see how to examine that location. however, both machines are identical, unmodified, off-the-shelf with the same graphics facilities.
I installed opting for KDE.
Hi
What about the 42.1 system?
Duh!
Good point!
omega:/sbin # /sbin/lspci -nnk |grep -A3 VGA
04:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF108 [GeForce GT 620] [10de:0f01] (rev a1)
Subsystem: eVga.com. Corp. Device [3842:2625]
Kernel driver in use: nouveau
Kernel modules: nouveau
I think I lied - after looking at that output I checked again and I see that the above-tested system indeed has an added video card while the system showing the problem has the video connector plugged into the motherboard.
Further info:
I booted from an old 13.1 system on the machine showing the problem and it identifies the video as:
sigma:/ # /sbin/lspci -nnk |grep -A3 VGA
01:00.1 VGA compatible controller [0300]: Matrox Electronics Systems Ltd. MGA G200EH [102b:0533]

Hi
Not sure how well Plasma works with the older card… At the grub boot menu, press e to edit on the linux line and try adding nomodeset, or just boot in safe mode and see if it comes up.
Thanks. I’ll need to try that later today and will let you know.
I got into the GRUB editor but am not familiar with it and did not see how or where to add nomodeset. Can you give me more detailed instruction on that?
Also, I redid the install setting SSH active in the setup screen and can now SSH in from another machine if that helps us.
Thanks.
AHA! I found a thread that described adding nomodeset at the GRUB editor and that indeed worked. Thank you!
Any further advice on any better final solution for this issue?
Hi
Try setting a different window manager, eg icewm (via YaST /etc/sysconfig editor) and boot without the nomodeset, if that works then it’s a graphics card/plasma issue…
Will-do. Thank you.
No luck I set it to icewm and had the same result.

Hi
Hmmm so it’s at the login screen (sdm?) or at the desktop (window
manager)?
Might be a boot with nomodeset if you can live with that?

Is there a way to make it boot with nomodeset without having to enter it in the GRUB editor every time?

Hi
Yes, YaST -> System -> Boot Loader Kernel Parameters tab, then in the
Optional Kernel Parameter line.

Well, I do see one additional problem. On the 42.1 system or on this system running 13.1, graphics on the screen are “squished” i.e., circles become ellipses. This can be fixed by changing the screen settings from "Scaled to “Scaled and cropped.” On this system running 42.2 under nomodeset, the images are similarly distorted, but changing to “scaled and cropped” has no effect. I’m guessing this is do to the nomodeset. Is there a fix for this?
