AMD Radeon OpenCL

@Marcsitkin

This was 21.50, where can I get the 20.50? I'm only seeing 21.40 on the previous versions of the AMD site.

@Marcsitkin

I haven't updated a kernel on ZOrin. Do I need a tool like mainline? or is there a utility in Zorin. Also, is the kernel selectable in GRUB at boot. Thanks

You can try the guide here:

[HOW TO] Easily install the latest available Kernel When you have Net Connection

UPDATE: As of 20 Aug '23, I have tested this method and found that although the kernel packages appear to install just fine, the Software Updater soon alerted me that I had broken packages. Checking, the latest kernel I tested (6.4.11) had dependency issues due to the later kernels requiring libc6 > 2.35 I recommend using the TuxInvader Mainline kernel for any users that run into this issue. sudo add-apt-repository ppa:tuxinvader/lts-mainline sudo apt update Look at the available packag…

As this will help ByPass the Libc6 error.

@Marcsitkin

Also, is the kernel selectable in GRUB at boot. Thanks

Yes, absolutely. But if you install a Later Kernel, it will automatically boot into the latest kernel unless you take steps to not have it do so:

[HOW TO] set an older kernel to default boot

You may need to use an earlier kernel than the current kernel used by Zorin. This method allows you to set the kernel that you will boot into by default. To set the new kernel to default: Boot into the kernel you wish to be Saved. Open terminal and run: sudo nano /etc/default/grub Change GRUB_DEFAULT=0 to GRUB_DEFAULT=saved Hit enter to drop down a line. Add GRUB_SAVEDEFAULT=true ctrl+x to exit, then the y key to say yes to save, then the enter key to save as current configuration. Ru…

[Marcsitkin]

Just to be clear (I'm an old man you know)
Do I need to undo anything I've done to date prior to taking these actions?
Is the kernel install the first step?
Am I starting the process over with the driver installation?
Thanks

[Aravisian]

@Marcsitkin

Is the kernel install the first step?

The installs can be done in Either order.
If it was me... I would remove any previous installs of AMD Drivers - Just to be Sure... Since there are times when having multiple AMD drivers can conflict with each other.

Installed kernel 5.16 xx, downloaded the 20.50 PRO drivers and ran the install:

Am I getting closer? I'm done for the night, thanks, please let me know if there is something else to try.

[Aravisian]

Well, so much for that method avoiding the Libc6 dependency error...
So annoying. Ubuntu could fix that so easily... and simply refuses to do so.
Let me research and ensure a safe method of install without that error that you can reference in the mornin.'

[Aravisian]

This post reminded me of Liqourix Kernel, which I had forgotten about:

Kernel is not patched for FSYNC

Thank you for the response, i ended up installing it again, sudo add-apt-repository ppa:damentz/liquorix && sudo apt-get update sudo apt-get install linux-image-liquorix-amd64 linux-headers-liquorix-amd64 everything seems to be working fine at the moment with FSYNC enabled once again, still strange as to why it was removed to begin with, anywhere ive been reading is indicating that this is a feature installed with the kernel itself, the last update obviously removed/disabled it somehow . Ch…

Details and install here:

Liquorix Kernel

The other option is to use the indomitable Tuxinvaders's patched kernel:

sudo add-apt-repository ppa:tuxinvader/lts-mainline -y

sudo apt update && sudo apt install -y linux-generic-5.17

[Marcsitkin]

One question- with the use of a patched or out of repro kernel, what happens with upgrades? Do the kernels get point upgrades, does Zorin install new kernels automatically, and does the AMD driver package need to be reinstalled?

This just came up- EVGA GTX 1060 3gig available which fits my computer and power supply capabilities. Perhaps this is a way forward? Moves me off AMD to NVIDIA. Performance is a little better, and price /local availability is good. Am I right in assuming that swapping cards and installing the NVIDIA drivers gets me past the AMD mods we've done?

[Aravisian]

@Marcsitkin

Am I right in assuming that swapping cards and installing the NVIDIA drivers gets me past the AMD mods we've done?

Yes, it would since it bypasses the AMD issue entirely.
I am running EVGA GTX 3060 - it has a bit more vRAM in it. It works flawlessly on Zorin on the current Zorin Kernel.

@Marcsitkin

One question- with the use of a patched or out of repro kernel, what happens with upgrades? Do the kernels get point upgrades, does Zorin install new kernels automatically, and does the AMD driver package need to be reinstalled?

The system will defer to the higher kernel. In this case, the Liquorix and the TuxInvader mainline kernels both are higher kernel versions. So even if Zorin OS updates push through a kernel upgrade, the higher installed kernel would remain the priority kernel booted into.
So, you would not need to reinstall the AMD drivers, since the higher kernel would not be replaced.
Both the TuxInvader and Liquourix kernels use DKMS. That should be fine... So, that really boils down to whether the installed AMD drivers were installed against DKMS and whether the TuxInvader or Liquorix kernels get upgrades.

That was not one question...

[Marcsitkin]

Well, it started as one question...
Thanks for the multiple answers.

I'm going to see If I can get that Nvidia card. Will keep you posted!

[Marcsitkin]

Me again. GTX_1060 Nvidia card is installed, powered up, Zorin booted on nouveau drivers. Many proprietary drivers to choose from. Advice on forum is to use newest for cards after 2013. Would that be 510 on the 5.13 kernel?
Thanks

[Aravisian]

510 is fine - that is what I am using, too.

I recommend avoiding the 470 (Proprietary Tested). It has had a lot of problems reported with it.

[Marcsitkin]

So far so good. OpenCL is working, double checked with a darktable export, seems good there as well.

Thanks for all your help. I'd like you to do the honors of selecting the "Solution" thread.

[Aravisian]

I am new to Linux. Though I am closer to two years in, now... I still consider myself a novice.
Not long ago, when I switched over to Linux from Windows, the general trend was that Nvidia was troublesome.
Change is a funny thing, because changes can often happen quietly in the background and not everyone gets the memo. Nvidia experience on Linux has rather quickly improved in the last year and a half or so.
Which really is a good demonstration that our ideas and recommendations on the forum need to stay Up To Date.

I marked the solution for your post in which you opted for a better supported graphics card.
