[qubes-users] 4 monitors, 3 output types, 2 graphics chips and not getting to show up on all 4 monitors
I have finally gotten around to re-tackling my multi-monitor/multi-graphics chip issue. I have decided to try booting a few different live distributions to see what happened, here is what I have in terms of hardware: Four monitors, 2 HPs 2 Dells. HPs are in landscape position, Dells are in Portrait position The monitors accept VGA, HDMI, and DP One chipset is on a graphics card, and is an AMD Radeon HD 6570 1GB DDR3 PCIe x16 - 1 DVI and 2 DP out ports (I think it came out around 2013ish?) The other is an integrated intel chipset - 1 HDMI and 1 DVI out ports Qubes 3.2 isntalled Live distros I have tried: Fedora workstation 28 Fedora workstation 27 Xubuntu 18.04 Kubuntu 18.04 Fedora KDE 28 Mint xfce 18.3 CentOS GNOME 1708 CentOS KDE 1708 Results so far: Qubes 3.2, installed: All 4 monitors "light up", getting some sort of signal i guess, but the one with DP in will not show anything, just like one half of that screen is light, the other dark. I can't get the two Dells two rotate to poitrat mode. Strangely I don't get icons on any of the menus now. A few times I was able to go to "Display" and try to rotate the displays but when I did the DP display would go nuts and show something like still static... or something, and now when I try to bring up "display" it comes up then instantly turns off... hence, I am not able to access the display window gui. Am not sure about if there is a command line option. And something I just found out, my power saving kicked in and on the monitor which shows nothing (Dell, poitrait, with DP in plug) was the only one that would show me a login... Fedora workstation 28 First, really buggy, made it hard to use, I am not sure if it was my setup or what *BUT* _all 4 displays worked_, until I started messing with the display option to arrange and rotate them into a usable configuration. Moving the tiny little display icons around was a challenge as they kept "slipping" and not moving where I was trying to drag them. I could get them into position (not rotated) but then I would move my mouse like to the edge of the screen and crash, back at the loggin, which would automatically then take me to a "welcome to fedora" window. At which point I am not able to reopen the settings/display box (just does nothing when I click on settings). Mint xfce 18.3 While mint was more stable, the arranging of the monitors in the position I wanted was just as diffiult as Fed28. And like Fed28 eventually the display option window was... no longer an option, it would instantly crash after trying to open it, not sure what would cause that. Though, like fed28, all 4 displays "showed up" I just could not arrange them into a usable configuration and the more I tried the less stable the display program/window got. Kubuntu 18.04 With Kubuntu, one of the main things I noticed was it flashing a message "Firmware Bug: TSC_DEADLINE disabled due to Errata; please update microcode to version 0x22 (or later)" maybe this is part of the problem? ... regardless, I have no idea how to do that... pointers? Next, when booting up, the Dell w/ DP in was flashing... funny, the flashing kubuntu icon on that display wasn't displaying properly. I tried rebooting and then it just crashed, didn't even get to a gui Fedora workstation 27 Got the same firmware error from Fed 27, that and I could not even get to a GUI first (second, third, etc tries). And something I had not encountered before, when I tried rebooting it would reboot back into the same frozen screen, even when I turned the comp off (removing the usb flash and shuting off then turning on resolved that). Fedora KDE 28 similar firmware error. asked for login from the start? Couldn't find any hint of what it might be on the net. bizarre, moot here though I guess. Xubuntu 18.04 Went great... until it didn't. Booted up fine, but then when I tried to rearrange the displays it logged me out, apparently paswd was ubuntu. next time I tried booting xbuntu live, when it went to the gui booting screen 3 of the 4 displays looked ok, but the Dell DP display was off in terms of color, after that... the two HPs just had a blinking cursor, and the two dells kept blinking the firmware error that most of the distros are giving me, couldn't get any further. CentOS GNOME 1708 Booted up nicely enough. Was able to arrange the two HP (integrated intel gfx) no problem, the Dells were not on by default in the settings, when I tried enabling them, they went to like a strange static display of rainbow noise if that make sense. Didn't matter if I tried to set the two dells (secondary gfx card) to mirror, primary, secondary... nada, except static. CentOS KDE 1708 Started up recognizing all 4 displays... kinda, the two Dells, connected to the external AMD gfx card showed up with the same rainbow noise that happened in CentOS GNOME. Here they were recognized right off, in costos gnome I had to enable the two dells. Even though

It might be hardware, like your graphics chips might not have enough memory to drive all the monitors. - What happens if you only use 2 monitors on a single adapter? Try both adapters alone. - DP monitor by itself? - Windows 7? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

In testing other distros I was hoping to narrow it down, but I am still not sure, really not hip on trying win7 (or others) as I don't have a copy laying around, and linux live distros are so much easier ;) In some of the live distros I tried, I was able to get a display on all 4 monitors so I am thinking mem isn't the problem (flawed reasoning?) If I try two displays on the integrated adapter then those two work, more or less without a hitch. Some of the distros don't seem to like my (external) graphics card at all, and some just seem to take issue with the the monitor connected via DP (I have also tried a DP to DVI adapter I had laying around, nada still issues). I have now tried installing Qbes v4 onto a usb flash drive. The xfce display window was the least buggy compared with most of the distros, but it seems Qubes 4 doesn't like my graphics card... or something. The two Dells connected to the exernal graphics card are showing that multiucolored static no matter what configuation I try (ie rotating, mirror [which worked well for many of the distros], primary display etc). So I am left with the possibility that its the graphics card but as some of the other distros worked I was hoping that was the wrong assumption... or maybe I am thinking about it wrong, maybe its xen that doesn't like the gfx card? (which is the only thing I can think of that *all* the distros did not have). I am desprate to get a multi display option working, so am willing to get another gfx card but as I can't keep doing that I need to be sure next time.

What if you try Qubes with only the AMD adapter? It usually works well with the older ones (pre-Vega). Is it only when you use both adapters at the same time? I'm wondering if some distros default to a lower colour depth/refresh rate. > So I am left with the possibility that its the graphics card but as some > of the other distros worked I was hoping that was the wrong > assumption... or maybe I am thinking about it wrong, maybe its xen that > doesn't like the gfx card?
