SOLUTION:

I was missing this package sudo dnf install rocm-hip-devel as per instructions here: https://fedoraproject.org/wiki/SIGs/HC

Hi, I'm trying to get GPU acceleration on AMD to work in Blender 4.1 but I can't seem to be able to. From what I've seen it should be working with ROCm just fine but I had no luck with it.

I'm using Fedora 40 GNOME with Wayland and my GPU is RX 6800 XT.

System is up to date. I've also installed all these packages:

sudo dnf install rocminfo

sudo dnf install rocm-opencl

sudo dnf install rocm-clinfo

sudo dnf install rocm-hip

and restarted system after.

rocminfo gives me this

rocm-clinfo gives me this

I put my laptop into sleep by just closing the lid and sometimes after wake up the clock shows wrong time and date which results into web sites not loading until I change it back and then I also lose logins to my previously logged in websites and have to re-enter the logins.

I don't have dual boot so it's not Windows messing with the Linux time issue I was able to find.

I use automatic time and date with my time zone selected. Not sure what I should do about this.

I've tried to enable RTC in local time zone but that made things even worse so I disabled it again.

When they are already finishing each others sentences.

I'm unable to pair my Wacom tablet to my notebook via BT. I think I know the root cause of the issue which is the version of Bluez being 5.64 and the behavior of the issue is the same as I had on Fedora on my main PC few months back when I've tried to pair PS5 Dual Sense controller.

I was able to fix the issue on Fedora by downgrading the Bluez version with "sudo dnf downgrade bluez" but on Pop!_OS this does not work and neither I was able to upgrade to one of the newer versions 5.65 or 5.66 (it says I need to compile these?).

I'm new with Linux so I'm not sure how I would go about compiling something to make it work. The 5.65 version seems to have bugfixes for my issue but I'm perfectly fine with downgrading to anything older as long as it works if it's simpler to do.

To describe the issue:

When I put tablet into a pairing mode it will appear in the Pop!_OS system and I can select it to pair. It will attempt to pair but then fails.

I've tried to force it to pair with "bluetoothctl trust/pair/connect MacID" commands and it managed to say "connected" but the tablet was still not responding and the LED was blinking as if it was still in pairing mode. I've also tried the Blueman GTK BT manager with no luck.

Note: It works perfectly well via USB connection. It also connects instantly to my main Windows PC via BT so the tablet is not at fault.

EDIT;

FIGURED IT OUT

by default laptop was non-discoverable and there is no system setting on either Pop!_OS or Fedora to make it discoverable. Had to use Blueman to make it so. I've only noticed that when doing "sudo systemctl bluetooth" for XYth time and there was "Disoverable: No" next to one of the MacIDs. After figuring out the ID belongs to my laptop I just had to figure out how to make it discoverable and turns out Blueman can do it.

• RED = Thermal Grizzly Carbonaut
• GREEN = PTM 7950 (no idea if the original or some fake but it works, bought from random seller on Aliexpress)
• before Arctic MX-4 was hitting TJmax 110C at 312W (good temps comparable to Carbonaut for first few days after application then drastic increase in short time due to pumpout issue)
• stock paste was hitting TJmax 110C at 255W (when I got the card it was used and already almost 2y old)

Unfortunately I don't have any data for the MX-4 and stock paste to put in the graph.

Testing was done with TimeSpy GPU Test 2 on a loop for 10 loops.

Anyone can help me? I wasn't able to find any solution for this. The controller works via USB-C just fine but I only have a very short cable, I borrowed the controller from a friend to try it and don't have the original cable but I was intending to play via Bluetooth anyways.

Basically, I can find the controller via pairing mode but when I try to pair it I get error:

The Setup of Dual Sense wireless Controller has failed.

After that I can see it in available wireless devices but when I try to connect to it it will immediately disconnect again, checked with bluetoothctl.

Using on-board Intel AX200 wireless controller.

I switched from Windows to Fedora last week and I'm monitoring the stats with Mangohud when playing games. I used to run HWinfo on 2nd monitor when using Windows 11.

I have 6800X ( default voltage) . The card maintains higher clocks at lower power most of the time. I've set the same OC as on Windows with a 2700MHz max clock and in games I'm sitting pinned at 2670MHz-2700MHz almost all the time in Linux when I don't hit power limit (312W) while on Windows the actual clock barely went over 2600MHz and card was almost always bouncing off of power limit resulting in massive clock drops to 2300-2400MHz. On Linux the drops go down just by like 100MHz-130MHz at most in the same scenarios.

Unfortunately I'd need to install Windows again and do proper testing to compare but I wonder if anyone else can confirm/deny this to me.

At least on idle I can confirm for a fact that the card uses less power, usually around 30-35W while on W11 was like 40-50W.
