Hello Teh. I'm hoping there are still people here who pay enough attention to hardware to help with the following...
My sister has a Dell Precision WorkStation 390 with NVidia Quadro FX 550, connected via two DVI ports to two screens.
It was running Windows 8.1 Pro without issues, and it runs Debian without issues, but she was required to upgrade it to Win 10 for her work, who are arseholes. Anyhow, because Windows 10 is a pile of shit the resolution is now limited to 800x600.
Tried installing the relevant drivers from Nvidia (both U8 and U4), and they appear to work ok upon initial install, but after restarting there's glitches and flicking in the menus/etc. (Also tried older drivers from Dell; no luck there either.)
I figure the possible options are:
1. Attempt to run Windows 10 inside Debian via KVM/QEMU.
2. Spend ~£20 on a replacement PCI Express graphics card that explicitly has Windows 10 drivers available.
3. Spend ~£200-250 on a replacement refurb unit or an NUC.
The first option is not really a viable one - particularly since it isn't clear how well multi-monitor stuff works (seems the second screen would be display-only/non-interactive), but it also introduces significant potential for other issues to crop up, and may need a RAM upgrade to get acceptable performance (which removes its benefit of not costing money).
Option 3... well, I would rather not spend 10x the amount just because Microsoft suck. (There are cheaper refurb notebooks, but their screens are too small and I doubt they will drive two external displays.)
So, unless anyone has any better ideas, I need to figure out how to determine which graphics cards are suitable and compatible, then find one on eBay.
The mainboard is a "Dell 0DN075" (which I presume is same as "DN075") and Inxi reports that the PCI slots are:
Slot: 1 type: x1 PCI Express SLOT1 status: Available length: Long
Slot: 3 type: 32-bit PCI SLOT3 status: Available length: Long
Slot: 4 type: x4 PCI Express SLOT4 status: Available length: Long
Slot: 5 type: 32-bit PCI SLOT5 status: Available length: Long
Slot: 6 type: 32-bit PCI SLOT6 status: Available length: Long
Slot: 10 type: x16 PCI Express PEG status: In Use length: Long
I'm guessing the "x16 PCI Express PEG" one marked "In Use" is the current card and the rest are irrelevant? (Pretty sure there aren't actually that many physical sockets on the board.)
In any case, last time I upgraded a graphics card was when AGP was a thing, and none of my searches are bringing up anything remotely useful.
Can anyone help?
