similar to: 4 monitors with one graphics card and standard driver

I have a user who wants to have 4 monitors attached to his CentOS 6.4 system. I know that you can't use both on-board video and a PCI video card at the same time, but what about two PCI video cards? The system seems to recognize them as shown by the lspci -v output below, but I can't get Xorg to use the second card. Has anyone done this? If so, what is the trick to get it to work?

So, after some discussion of our new control workstations, we are iterating in on a solution; we are looking at a 1U short-depth SuperMicro SuperServer 5017R-MF with a graphics card in the PCI-Ex16 expansion slot. However, the display requirements have increased to 3 or more monitors for future expansion, so I was wondering whether anyone had any experience with triple- or quad-display single card

I have an unusual use case. I wonder if anyone can help. We use a PC with 8 HDMI outputs for powering a video wall in an operations centre. We use two Matrox video cards, each with 4 outputs. "lspci" reports these cards as" [AMD/ATI] Cape Verde PRO [FirePro W600]". On an older version of CentOS 7, I used the proprietary AMD/ATI driver. This had a utility (I roorget the name)

User got upgraded to 6.4. Graphical mode video fails. It's an AMD (nee ATI) RV620 (FirePro 2260). So I finished upgrading everything, including kmod-fglrx. Based on the xorg.conf's on there, it's been using the fglrx. Now, in Xorg.0.log, it tells me "no supported AMD display adapters were found". I've been on-and-off googling for hours, and can't figure out if the

Well, I got my user back to being able to use his system, but I've still got one issue: it's running on the VESA driver - there is *no* Catalyst build for this monitor, for CentOS 7. From a lot of googling, nothing's been done since the summer of '14 (lspci reports it as a FirePro V3900). Any thoughts, or pointers, as to if/how I can get X - he's running KDE - to see the full

I''m using Xen 4.3, installed from source on Ubuntu 13.04. I''ve successfully installed a Windows 8 guest, and had Xen pass it an AMD FirePro W7000 GPU (technically 2 PCI devices - the second is for the sound), as well as the virtualised graphics adapter. Windows finds the card fine, and I''ve installed AMD''s drivers. Device Manager says that the card cannot

Hello- I installed CentOS 5.5 on a DELL Machine with ATI Firepro 2260 graphics card. I'm using GNOME for the graphical environment but the display is refreshing very slowly, e.g. scrolling a webpage or moving a window around. Any idea how to solve this issue.

Hi all, I have made some tests to find a good driver for FirePro V8800 on windows 7 64bit HVM. I have been focused on ''advanced features'': quad buffer and active stereoscopy, synchronization ... The results, for all FirePro drivers (of this year); I can''t get the quad buffer/active stereoscopy feature. But they work on a native installation. The only driver that allows

I built guest vm's one for Windows 7 and one for Windows XP using the virtual machine manager on a just updated to centos 5.7, and they are both crashing the host machine. They run only for a few minutes, but suddenly freeze, crashing the host. There is no networking. No X. No way to drop out of X. The only way out is a hard reboot. I don't see anything in the logs -- messages or

Since my current monitor appears to be slowly dying, I'm looking for a replacement. I generally use hardware replacement as an excuse to get something bigger/better/faster than what I had before, so I'm currently considering something like a BenQ GW2765HT. The manual for my Intel motherboard has this to say about DisplayPort on the built-in graphics controller: QUOTE: DisplayPort?s

I was reading the Wiki page here: http://wiki.xen.org/wiki/VTd_HowTo don''t know how updated it is, BUT at the top it said: -------------------- -------------------- -------------------- -------------------- -------------------- -------------------- _Xen 4.1 xl tools notes _ * Only devices with FLR capabilities are supported. * Passing through a PCI card without FLR capability

I am trying to assemble or purchase a set of CentOS 6 compatible SFF workstations, and am finding it incredibly frustrating to do so. hardware.redhat.com is so slow as to be useless and provides almost no information about each of the 1,300 or so products listed in their database; clicking through them one at a time is incredibly frustrating (and about half of them are discontinued or out of stock

Cracked this. The solution was that I needed to specify the correct driver ("radeon") in the xorg conf file to use the open source driver, e.g. Section "Device" Identifier "aticonfig-Device[0]-0" Driver "radeon" BusID "PCI:1:0:0" EndSection All the other bits from the conf file I could keep the same as before.

I have an old dell 2450 that was running kernel 2.6.18-308.1.1.el5 I then upgraded it via yum to 2.6.18-308.1.1.el5. Now when the server boots to the new kernel, 2.6.18-308.1.1.el5 it hangs on "starting iSCSI" and the weird thing is when I tried to switch back to the older 2.6.18-308.1.1.el5 kernel it works fine but the network script fails to start. I'm not really sure what I should

Dear Devs, We have achieved a desktop of up to six monitors, with openGL running succesfully on the desktop, with the following setup/features: * Ubuntu 16+ * Xrandr * Noveau driver * Two gtx750 graphic cards Each (identical) graphic card has 2xHDMI + 2xDVI connectors, which we connect to the monitor array. So far it works with six monitors, but we'd like to achieve eight. However,
