Yast2 bootloader - switching to kernel parameters freezes yast

Hi, I recently got a new graphics card to replace my old one (the old one being a 7800 and the new being a R9 380 - both AMD cards).

After I put in the new graphics card, the system booted fine, but now if I want to change the kernel parameters I can’t.

As soon as the bootloader module is loaded and I switch to the kernel parameters tab it freezes. Starting from the console didn’t produce anything on the command line.

I don’t really know how to debug yast, any ideas?

Edit /etc/default/grub, variable GRUB_CMDLINE_LINUX_DEFAULT, and run “update-bootloader --refresh”. You can also start text mode yast using “yast” in terminal.

Ncurses yast freezes in the same spot.

I can workaround the freeze by manually editing files, but I’d much prefer it to work - Yast is pretty integral to openSUSE.

Is there some procedure for upgrading graphics cards that needs to be followed for everything to work afterwards or something?

At the Grub2 menu, select the entry by using the up/down key and “e” <for edit> (without the quotes).
Use the arrow key to navigate to the linux line ending in vga=795 or whatever your setting is and type: nomodeset

Press the F10 key to start the boot process.

FYI
Try installing the AMD/ATI drivers provided via the Yast Software Repositories.

Disabled mode setting does allow the Yast module to load. So at least I can do that and use Yast before putting it back how it was.

Thanks for your help!

Your are welcome.
I used to experience freeze ups with my Nvidia card when running Q&A with Leap’s milestones and betas.

Hopefully, once you get the proper drivers and updates installed the freeze up should disappear.

I would recommend that you enable your DEBUG repositories. If you keep experiencing
freeze ups or crashes you’ll be able to report them to Bugzilla or https://bugs.kde.org.

Good luck!
