It still depends on the hardware you have. If you have hardware that’s fully supported by the kernel version your distro is running, then it’s easy. But as soon as you add a piece of hardware that isn’t, there’s a good chance you need to spend a lot of time searching how to fix it. Buying a new mouse and all of a sudden not having sleep work is not a power user problem IMO.
Native Sliding Sync (AKA Simplified Sliding Sync) was just released to Synapse and Element X over the past couple of weeks. It’s not an exaggeration to say that it is FAST now. My fairly large account usually syncs instantly now. If not instant, the longest I’ve seen was 1 second. Give Element X a try again (assuming your home server supports SSS).
