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.
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.
