  • This seems similar to the spammers who deliberately use bad spelling and get significant facts wrong in their scam email. They don’t want someone who understands things to get to the second stage and waste their time they are trying to get dummies who will fall for it.

    I think that the company in question would treat their employees badly and they don’t want someone to accept a job offer and then quit when they learn how abusive the work environment is.










  • There’s really no difference between running Linux on desktop and laptop systems. As you have done it in a desktop the laptop will really be no big deal for you.

    Sometimes drivers aren’t quite as good and maybe battery life won’t be as great. But laptop batteries last for ages nowadays so even a small reduction won’t hurt for most uses.

    I’ve run a fleet of Linux laptops when doing corporate IT department work and run more than a few for myself and helped out friends. Generally everything works well enough.





  • Thanks for the advice, I installed the Debian package “read-edid” and used the get-edid program from it to get the EDID from the monitor. Then I installed the “wxedid” package to display it graphically because the parse-edid program from read-edid didn’t work well. According to wxedid there’s a seletion of 38402160 modes and some 40962160 modes. So it seems that the EDID is the problem.




  • 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.
