The FS feature is great, it’s just cumbersome to use without a tool.
Snapper works well for a local backup like history both against botched updates and accidental deletion, but eats up the free space with the default settings.
Timeshift is an easy to use GUI but doesn’t support non-default partitions.
Also the quota support had a nasty side effect: freezing the whole system on snapshot deletion.
It’s hard to live up to expectations after Frieren but here are some that were memorable for me:
I think calling it a “cache” is not precise. The primary function of the DRAM is to hold the dictionary for translating logical addresses (e.g. sectors) from the OS to the physical addresses (which NAND chip, which bank etc.). This indirection is needed for the controller to do wear leveling without corrupting the filesystem.
On a SATA SSD without DRAM each read IO could mean 2 actual reads: first the dictionary to find the data and than the actual data being read. As you said HBM helps by eliminating this extra read.
The read and write caching is just a use of the remaining DRAM capacity. Since modern Operating Systems use the general RAM for the same function it is usually just a small increase to the throughput.
if the integrated one is good enough for gaming
No, the iGPU is only meant for testing and basic desktop usage like video playback on the 7000 series. There are 8000G series with better integrated graphics but even those are much weaker than any dedicated GPU.
Could you tell us more specifically what do you want to use/play on this PC? (e.g browsing or productivity apps, or old games or the latest AAA titles)
A maximum budget would be very helpful.
If you are looking to reduce the build’s cost consider a cheaper motherboard or a used GPU. The Asrock B650M-HDV/M.2 is the lowest you should go if it has all the connectors you need. As for buying used video card it’s always a bit of risk, but as the most expensive component you could save the most on that. Since all AM5 CPUs have an integrated GPU you could build without the dedicated GPU first.
Maybe you could use a USB keyboard or mouse connected trough a dock or OTG converter to allow file transfers.
There is an even more relevant video of using external storage trough USB. He recommends using software raid:
Are both drives fully encrypted with LUKS? Is trim enabled in both crypttab and fstab?
Thanks for the links! I updated my config from z3fold to zsmalloc and adjusted the vm.page-cluster to test these out.
Reading a bit more, I think when using large max_pool_percent (>30) with Zswap the two solutions are more similar than not. A crucial difference is what use-case is more acceptable since Zswap can cause unresponsiveness (and potential lockup) under high memory pressure. While Zram could result in an OOM crash in a similar worst-case scenario.
It is possible, it’s just not generally supported be ISP routers. Also there is a possibility of performance issues since IPv4 NAT often relies on hardware acceleration which might not work for NAT6.
Stormgate
It’s like 90% StarCraft 2 and 10% Warcraft 3. The competitive RTS part is promising but it didn’t show me anything new. Depending on the lore and campaign it may get more interesting, so far it’s neutral.
Millennia
It starts very similarly to Civ 6 with even more kinds of resources. The current version of the UI seemed confusing and the poor performance (on linux) stopped me from finishing the demo.
Even tough IPv6 is technically superior to IPv4 for the network operator it doesn’t have clear benefits for home users.
Having global addresses instead of NAT means less control over your LAN and these unique public addresses can track users more accurately.
Btrfs with compression enabled and subvolumes set.
And enable/automate maintenance services for BTRFS. For example: balace should be run on heavily used system disks or scrub could help detect errors even on single disks.
ZRAM (With proper sysctl.conf like PopOS does).
Could you explain the preference of ZRAM over ZSWAP? I thought the latter was the more advanced and better performing solution. Is there some magic in Pop’s config?
Happy to help! Tough you are right, this is a rather generic error that doesn’t help much just confirms that the GPU is the issue.
At this point it could be a driver issue since there are similar open bug reports. A hardware problem is still possible since you previously said that it’s unstable on windows too, and power related issues can also lead to this error message.
Most distros use systemd and its logging solution: journald. You can use journalctl to read the logs around the time of the crash for e.g.:
journalctl -S -5m this shows the last 5 minutes. Use this when a game crashes but the system continues working and did not reboot.journalctl -b -1 -S -10m this shows the last 10 minutes from the previous boot. Use this if the crash froze the whole system and rebooted.Look for red lines (errors) and what wrote them. AMD GPU faults usually have the ‘amdgpu’ mentioned, memory errors could appear as ‘protection fault’.
Did you check the system logs to see what caused it?
Many things can result in seemingliy random crashes. Any overclock (including XMP and Expo) or undervolt or even a bios version can be problematic.
I would check first if it’s stable on windows.
What filesystem are you using? Is it encrypted?
Could you run a benchmark to verify if reads and writes are both affected? KDiskMark is like crystaldiskmark or Gnome Disks has a built in benchmark.
Do I need to disable compression on my swap subvolume?
Short: No
Long: it doesn’t matter when mounting multiple subvolumes of the same btrfs partition the options from the first one (usually /) will apply to all. So even if you disable it, that will be ignored.
The old way of creating swap shows the chattr +C line which disables CoW. The same method should work for your Downloads folder since CoW is needed for snapshotting.
The mobile and TV clients are often limited to the codecs with hardware acceleration. Or just selecting a lower bitrate on the client will cause transcoding.
