Radeon Graphics Question

English Install/Boot/Login
#1

I **upgraded **(not installed) openSUSE 13.2 to Leap 42.2 today. To get the upgrade going, I had to use F3 on the boot screen to set the Video Mode to “No KMS”. After that, the upgrade was uneventful and successful

When booting 42.2, there is a brief message that says, “No UMS support in Radeon Module”. It does not stop startup and the display seems OK.

I assume I need to load some Radeon HD6530 D drivers. Can someone point me in the right direction for instructions?

Cordially,

I assume I need to load some Radeon HD6530 D drivers

The fglrx-Driver does not build with Leap 42.2, so you can only use the free Radeon-Driver from inside the Kernel.
This one is installed but “no KMS” (nomodeset) is preventing them from loading.

How to delete nomodeset see here:

Otherwise post:

cat /proc/cmdline

I followed the instructions in the post you referenced to delete nomodeset.

After reboot, the Optional Kernel Command Line Parameter was the same as before.

linux-ikia:~ # cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-4.4.36-8-default root=UUID=faa8aa50-d380-48cc-92e0-f75b79edb441 resume=/dev/disk/by-id/ata-WDC_WD5002AALX-00J37A0_WD-WMAYUJ652853-part1 splash=silent quiet showopts nomodeset resume=/dev/disk/by-id/ata-WDC_WD5002AALX-00J37A0_WD-WMAYUJ652853-part1 splash=silent quiet showopts
#4

Did you do that with Yast—System—Bootloader?

#5

Yes. I deleted the Optional Kernel Command Line Parameter and clicked OK from Yast > System > Bootloader > Kernel Parameters

The deleted code is:

resume=/dev/disk/by-id/ata-WDC_WD5002AALX-00J37A0_WD-WMAYUJ652853-part1 splash=silent quiet showopts nomodeset resume=/dev/disk/by-id/ata-WDC_WD5002AALX-00J37A0_WD-WMAYUJ652853-part1 splash=silent quiet showopts

(aside - why is there not code block feature when editing a post? I used the Quote block just to set it apart.)

Running the Bootloader a second time (no reboot) shows that the code is still there just like it was before deletion. Apparently the change is not being saved as it should be.

#6

Did you accept the changes just closing the window saves nothing

Also should not delete the line just nomodeset

#7

I deleted the entire line and clicked “OK” (the only other option was “Cancel”)

I will now just delete the word “nomodeset” click “OK” and get back to you with the results.

#8

That worked like a charm! Thank You for clarifying the instructions.

My display is now great, not just OK (readable).
