I’m having an issue with my desktop flickering after my monitors wake up on KDE. When I first turn on my PC it’s fine, but if I walk away and let the monitors turn off when I then come back the desktop starts flickering. It’s only the desktop that flickers, if I have an app open full screen it’s fine but as soon as I minimise it the flickering comes back. It doesn’t seem to be an issue if I leave it long enough for my actual PC to go to sleep, only the monitor. This happens on both Wayland and X11.

Does anyone have any ideas on how to fix this, and if not is it worth submitting a bug report on kde? Or is it probably just something dodgy in my setup? This is with an Nvidia GPU which I suspect has something to do with it (I’ve tried with both the nvidia and nvidia-open drivers). I’ve already had to change the settings so that the screen locks before the monitors sleep otherwise it was causing kwin to crash and I’d get stuck at the login screen for a minute after resuming.

I was planning on picking up Cyberpunk a while ago but noticed I no longer reach the recommended system requirements since the last update. Is it worth upgrading from a Ryzen 7 3800X to a Ryzen 7 5700X3d? The 5700X3d seems like the best choice as it seems like a pretty decent jump in gaming performance without having to buy a new motherboard. And although the 5800X3d would be even better it’s ~£300 compared to ~£200 for the 5700X3d so doesn’t seem worth the price difference.

My gpu is an RTX2080 super so that would probably become the bottleneck, but I’m planning on upgrading that a bit later on if I upgrade the cpu first (not sure what to go with for that either yet, I’m still debating between Nvidia and AMD)

Apart from the obvious nautical themed solutions, are there any ways around streaming services not allowing HD video playback on Linux? Prime video is the one I’ve noticed it with the most, I haven’t tried Disney plus yet but I’m expecting it to be similar. I’ve been dual booting for a while now and this is the main thing keeping me on Windows at the moment.

I’ve just installed Arch on my laptop and I’ve noticed the WiFi card seems to be generating a load of errors. I’m also dual booting Ubuntu server and it looks like that’s been generating similar logs although I’ve only ever used Ethernet on there:

Under Arch it has these 2 errors over and over again in journalctl:

Mar 31 00:38:58 Laptop kernel: ath10k_pci 0000:03:00.0: PCIe Bus Error: severity=Correctable, type=Data Link Layer, (Receiver ID)

Mar 31 01:13:08 Laptop kernel: pcieport 0000:00:1c.5: AER: Correctable error message received from 0000:03:00.0

And under Ubuntu it has this instead:

Mar 30 23:28:22 Laptop kernel: pcieport 0000:00:1c.5: AER: can't find device of ID00e5 Mar 30 23:28:22 Laptop kernel: pcieport 0000:00:1c.5: AER: Multiple Corrected error received: 0000:00:1c.5 Mar 30 23:28:22 Laptop kernel: pcieport 0000:00:1c.5: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID) Mar 30 23:28:22 Laptop kernel: pcieport 0000:00:1c.5: device [8086:9d15] error status/mask=00000001/00002000 Mar 30 23:28:22 Laptop kernel: pcieport 0000:00:1c.5: [ 0] RxErr

Lspci detects the card as this:

03:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 30) Subsystem: Foxconn International, Inc. QCA9377 802.11ac Wireless Network Adapter Kernel driver in use: ath10k_pci Kernel modules: ath10k_pci

But the chip itself is labelled as a Qualcomm Atheros QCNFA435 (which matches what the laptop specs are listed as online)

As far as I can tell the WiFi is working properly, is there anything I should do to fix these errors in either distro or should I just add the pci=noaer parameter to suppress the messages?

I needed a test VM at work the other day so I just went with Debian because why not, during the install I chose KDE plasma as the DE. I did nothing else with it after installing it and after leaving it alone for a while (somewhere between 20-60 minutes) the CPU useage shot up to the point vSphere sent out an alert and the VM was unresponsive (the web console just showed a blank console which I couldn't type in) It did this every time I booted the VM.

It seems to be the combination of vSphere Debian and KDE that causes this as I installed GNOME on the same VM and it was fine. I also created another Debian VM this time choosing GNOME during the install and that was also fine, until I installed KDE on that and then it started doing the same thing. I also created an Arch VM with KDE and that didn't have any issues.

Any idea why this combination causes issues? Journalctl output of the last boot from both Debian VMs below:

My current setup is a NAS running on an old Acer Aspire laptop with an Intel core i5-6500u and 8GB RAM (and an Nvidia 920m but I'm pretty sure its not using that as I'm running headless Ubuntu server and haven't installed the Nvidia drivers) with a 3.5" HDD plugged in via USB.

The main things I like about this setup are that its cheap (I already own it), fairly low power, and pretty quiet. I guess the built in UPS is a bonus as well!

The main reason I want to upgrade is so I can easily add more drives, either for redundancy or just more storage. The USB can also be a bit janky, sometimes after first powering on it fails to read the drive and I have to power off the hard drive caddy for about a minute, this does seem to be an issue with the devices itself though as I've had it do it with multiple drives in multiple PC's. It would also be nice to get the laptop back even though I don't use it much.

Currently its just acting as a NAS, but I would definitely like to set up Jellyfin as well. I'm potentially interested in hosting my own private Lemmy or Matrix instance, however since that would involve exposing my network to the internet I'd need to be 100% sure I could set it up securely so I may not bother. I might also set up a Minecraft server in the future but I don't have any plans to do that soon.

With those use cases in mind I figured low power draw is probably more important than loads of computing power. I'm really tempted by the ASRock N100M with either 8 or 16GB RAM, its slightly more powerful than what I've got now while being based on much newer architecture with a lower power draw. I think it would also allow for hardware transcoding in Jellyfin that isn't supported by my current CPU? Also fanless seems like a bonus. I'd probably pair that with the Fractal Design Node 804 which would come to around £250 total plus whatever I spend on a PSU. That would let me start off with 2 drives (which I already own) and easily add more with a PCIe expansion card later, however I'm not sure what power supply would go with this. It wouldn't need much power but there doesn't seem to be many options below 500W. Also is it worth going for a higher power rating with an 80 plus gold rating for more efficiency and potentially less fan noise? I did look at PicoPSU as a low wattage alternative but by the time you buy a DC power supply for it they seem to be not far off the price of a proper PSU for something thats a lot less capable, probably less efficient and looks very Janky. The other option is to go for the N100DC-ITX instead of the N100M as it used DC power instead of needing an ATX PSU, however that would limit how many drives I can add in the future as I'd need to find a way of powering them.

I've also looked at single board computers as another low power alternative. I was tempted by the Zimaboard or Zima Blade but the CPU on those seems outdated and under powered (it would be a step down from what I already have) and that really would limit me to 2 drives maximum. I also looked at the Odroid H3/H3+ but they seem to cost just as much if not more than the N100 options and tbh I think the cases are quite ugly. I'd rather stick with x86 than ARM unless someone can convince me otherwise!

With what I've said above do you think its worth upgrading to any of those options (or any other suggestions) or should I just stick with what I've got until it dies? Power supply suggestions would also be appreciated!

I undervolted my CPU about a year ago and haven't had any issues with it till now. I've been dual booting Linux recently and noticed whenever I was in Linux it would crash/reboot after a couple of hours or less of using it. I noticed the behavior was similar to when I set the voltages too low when initially setting up the undervolt so I disabled it and haven't had any crashed since. Any idea why it would be stable on Windows but not Linux? I tried a couple of different distros as well. I'll probably just raise the voltage until I get it stable again but I'm interested to know what could cause this! If its relevant my CPU is a Ryzen 7 3800x
