Hi,
I have a Supermicro X10SRA-F (with IPMI bmc with iKVM) and Nvidia gpu which is booting ok but after grub the local display is blank.
I loaded the optimized settings in the bios, then edited in bios:
1. IO --> PCIe/PCI/Pnp --> make sure ASPM Support is disabled, 2. set VGA priority PCI-E slot that you have the video card connected to. 3. Save the changes and reboot.
When I boot a fedora live dvd the video works. It worked a few times initially when I boot the ssd disk with the fedora installation. Now it gets to grub, boots kernel and then nothing but a blank screen, yet the screen does not go to sleep. It appears to still have a signal in fact and X for the mouse even was active twice.
Using a remote ssh connection and the iKVM I tried: -- reinstalling the Nvidia driver -- removing the proprietary nvidia driver and using nouveau but that had the same resulting blank screen.
These vga cards present are:
04:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 760] (rev a1) 0a:00.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 30)
While it is possible to reinstall the system and hope the problem disappears by default, I would much rather understand how to edit the display management configuration to make this work properly. Since the system-config-display was removed I have not learned how to edit the display options except for the basic display preferences dialog.
Additional guidance is appreciated.
Thank you, Kevin

In my experience these sorts of problems are best tackled by configuring the system to boot into multi-user.target instead of graphical.target and then using "startx". Also, looking at /var/log/Xorg.0.log may provide additional information on what may be going wrong.
Update:
I tested the fedora OS disk by removing the disk physically and connecting it to a completely different desktop, a dell with on-cpu graphics. I edited the video drivers and discovered that the Gnome gdm desktop manager continues to produce the same problem. I tested the Lightdm and kdm desktop managers and they are both working properly. I then placed the disk back in the X10SRA-F system and it is working correctly with the nvidia driver installed and using either the kdm or lightdm desktop managers. It is not clear why the gdm fails but I did find via google search that others have experienced this similar software problem with gdm. The X10SRA-F does not seem to cause any problem.
I tried to reinstall gdm, yum reinstall gdm, but this did not make an difference.

My understanding is that what you did only replaces missing or damaged files, and isn't as thorough as you might think it is. (I'm sure somebody will correct me if I'm wrong.) If I'm right, you may want to remove gdm completely, and then install it again. When you remove it, don't use -y because you want to know what else, if anything, goes with it.
Hi Jeff,
Thank you for the note. In the future I'll attempt what you wrote; to remove a package rather than reinstall. I needed to find a solution and get the systems to the users so I simply used the kdm. I discovered with kdm that the main display uses #2 (ctrl-alt-F2) and the other consoles become inaccessible to the local system display. These text consoles are instead available to the iKVM of the bmc controller. Yet in the iKVM the main display is not viewable (I think because it uses the PCIe vga slot.). Thus after opening the iKVM I need to use the soft keyboard, type ctrl-alt-F3 and will then see the text console and can use the keyboard. The affects the main display directly which is alos switched but inaccessible to the desktop display. The usability is not ideal but it partially works. Maybe this is the only option. I had the expectation that the main display and consoles could be available in both iKVM and desktop display but this may not be possible since there are two gpus involved. I'm interested to understand this functionality in more detail if anyone can explain. Please forward to a developer if you know who may understand.
Since I did not find any clear documentation on gdm and do not have any more time to troubleshoot further my only hope is that Supermicro, ASPEED and gdm or fedora developers could find a solution.
Thanks again, Kevin
