MAXSUN Intel Arc B580 Milestone 12G Graphics Card (MS-ARC-B580-MILESTONE-12G
The above is the cheapest card from my local store that has DisplayPort 2.1 (the rest have 1.4). It’s $469 compared to $199 for a RX 6400 or RX 6500. I can probably find somewhere cheaper to buy these things but I’m working on the assumption that the ratios of prices are going to be about the same.
From the Wikipedia page it looks like DSC is needed to do 8K@60Hz on DisplayPort 1.4. I think that is bad for text though.
That card has DisplayPort 1.4 which means that if HDMI doesn’t work then it’s limited to HBR3 which gives 24bpp@31Hz, which is barely adequate.
Also how do you set the bpp rates? The DisplayPort wikipedia page says that 24bpp and 30bpp are supported, but how do I even know which is in use?
The TV has built in NetFlix and YouTube so I don’t have much need for playing video from Linux. Currently YouTube is the only source of 8K video that I’m aware of.
I know it’s low end, I just don’t want to spend much money. It seems likely that one way or another I’ll find some problem with whatever card I get and want to replace it in a couple of years so I don’t want to spend much.
The card is documented as having HDMI 2.1.
Thanks for the information, that’s an unusual situation that you got yourself into. ;)
I had followed the advice of Dell support and unplugged everything including very unlikely things like NVMe devices and RAM and it still happened. It turned out to be the power distribution board.
I replaced the Power Backplane board J14R7 0J14R7 and it’s been running for just over 24 hours. As it was an intermittent fault I don’t count this as proof that it is fixed (I’ll wait another couple of days to be sure) but previously it never lasted 8 hours so it seems most likely.
The old Power Backplane had no puffy capacitors, no scorch marks, and no other indication that it was faulty. I also used all the same cables so it doesn’t look like a cable issue.
Thanks for your comment it helped give me confidence to spend the money on a new board. The other option I had considered was to just buy another system that would take the CPUs I bought.
The PSUs have lights on in the normal manner, they both have green lights when the machine is unresponsive. The power is probably OK, it works well enough for many other systems. The PSUs are configured in a redundant configuration, I’ve tried it running each of the PSUs separately and running both. Tried running both from a Y cable and from separate cables. I’ve tried switching the PSUs between bays. None of this changes it. But all on the same circuit.
There’s nothing in the iDRAC logs related to it or at the same times.
Thanks for the suggestions. I’ll try it on a different circuit but I have to put it back together again.
Reprogramming the 1000 other devices won’t be as hard as the first one but it won’t be trivial as they may be all on different versions of the software and there may be hardware variations too.
Just to triage the devices and determine which ones are good enough is going to be non trivial.
I’m continually mystified as to why companies don’t want to release the old technical documentation and software. Is it all so bad that they are THAT embarrassed to show it?
The changes for the company in releasing old software is minor, the vast majority of users don’t have the skill to deploy it and people who do have the skill can earn enough money doing a variety of technical work that repairing old phones isn’t going to be an attractive option.
What portion of phones capable of running LineageOS etc end up being used in that way? 1%?
The issue is the price of new hardware vs the hourly wages of people who are capable of reprogramming old stuff. If you are going to pay $100/h to get old stuff working and buying new stuff costs $20 then it’s cheaper to throw it out and buy new stuff.
It would be good if the EU could make USB-C docking functionality a requirement for all phones the way they made USB-C power a requirement. I doubt that Google could do it even if they wanted to.
As an aside Google REALLY doesn’t want companies to follow the example of Huawei with HarmonyOS. If any big player said “we will license HarmonyOS or develop our own thing if Google makes us do something we don’t like” then Google would give in.
Phones for desktop use is something I’m working on now. Not for old devices but for ultra portable work. I just paid $215AU for a Note9 with 8G of RAM. Until a couple of months ago my main laptop had 8G of RAM, that’s enough to do most non-server things you want to do with a computer.
For people who know as much about technology as most people in this discussion the thing to do if short of cash would be to buy a cheaper phone. I recently got myself a quite decent Note9 for $109AU and I could have got something even cheaper if I needed to. But many people aren’t as well informed, the above article is one example of people who are less well off being scammed by a corporation.
For my home workstation running Debian/Bookworm I started running Wayland-Plasma when Xorg mysteriously refused to work after replacing my video card. Wayland just worked and really had no issues for me so while I’m sure I could have solved the X11 problem I didn’t have a real need to.
I also changed my laptop to Wayland-Plasma more recently. A problem I had was in setting up the right modes for external monitors on laptops but that seems to work OK now. Generally things just work.
DSC is designed to be visually lossless not mathematically lossless - you could say the same about JPEG. There are many reports about text being rendered badly with DSC.
