All 4 monitors on the same graphics card is a good idea. You might also try a different DE than XFCE. I'm basing that on some past posts here, so don't have any specific recommendations on ones that better handle multiple displays. Disabling ME is specific to your hardware, and not really Qubes related per se. Only recommendation there is to carefully shop for Qubes compatible hardware that comes with ME already as disabled as possible, or older AMD hardware that doesn't have one. -- - don't top post Mailing list etiquette: - trim quoted reply to only relevant portions - when possible, copy and paste text instead of screenshots -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

I disabled hyper-threading, and the box feels more stable. But I am not sure if it was the problem.

Hi, the machine still crashed, so I need to give it a long memtest to see if it has any loose bits, but ECC memory should protect against such. Other suggestions?

Re: [qubes-users] wired problems with 4 screens and 2 graphics boards: ps/2 mouse and kbd lock up, machine still running, but not usable.
Also I bought a new old graphics board. Lets see if a amd firepro w5100 with 4 dvi ports is better suitable, as here the graphics board supports 4 screens out of the box, so x11 does not need to use 2 different graphics boards. btw how to make use of opencl in qubes?

Re: [qubes-users] wired problems with 4 screens and 2 graphics boards: ps/2 mouse and kbd lock up, machine still running, but not usable.
So thanks for the tip, I have now put videoram min to 36000 and overhead to 0. Lets see if the machine still bugs around. BTW, any thoughts on fighting the ME using qubes, so no more complete disassembly of laptops, de-soldering flash chips, soldering some small circuits to the south bridge and so on. Tricking around with the hw, is risky especially on a laptop, a honey pot approach might be a solution against the ME, but it is ring -3, that evil beast.
