Can't get higher resolution on Red Hat 7.2
Hi everyone,
recently I have installed red hat 7.2 (no-Cost RHEL for developers). After the installation I have booted into red hat and couldn't change the resolution of display (every thing is big now!) The only available resolution is 1024x768 and the monitor is unknown in the display setting. I have updated everything and it doesn't solve my problem.
I have checked the xorg direction (/etc/X11) and there is no xorg.conf, which can be normal I think (correct me if I'm wrong). I have searched about the issue and found out that I can create a xorg.conf file by running
Xorg -configure
Now when I run this command it fails with the following error:
Number of created screens does not match number of detected configuration failed.
I have also tried to use elrepo and installed xorg-x11-drv-intel but it didn't solve the issue either.
I don't know if it's relevant to the issue or not but at the system start I get the following errors:
FastTSC calibration failed
snd_hda_intel 0000:00:1f.3: failed to add i915 component master (-19)
I have a MSI Mortar Motherboard (b150m) and an Intel Skylake CPU.
I use the on-board graphic card of my motherboard and have no other graphic cards.
I'm trying for days now and I didn't find a solution.
Can anyone help me with the issue?

Hi Masood,
While you are waiting for RHEL 7.3 to drop, you could also test with a Fedora LiveUSB image (please use f24). This would enable us to see if the hardware works as expected there.
While it would not be an ideal solution, it may well be possible to temporarily run the hardware on Fedora and use either Boxes, or VirtManager to run RHEL 7.2 in a VM, until 7.3 is released, but still allow full use of the available video resolution for comfort on the eyes.

The Skylake GPUs have a hard time under 7.2 at the moment. I tried it fleetingly on my laptop, but it ended up using the VMware drivers for some reason, so would not support my external display or any resolution other than the native 1920x1080. I know that's more than you're getting, but the whole situation was less than optimal. As for F24, that's what I'm running now and things are great. I just hope that RHEL7.3 fixes things for Skylake GPUs as I really want to step away from the bleeding edge of Fedora with my laptop so that I can run things like Foreman proxies on the host OS and perhaps oVirt all-in-one too.
Update: Looks like RHEL 7.3 was released today. I'm off to try that.
The Skylake graphics support included in Fedora 24 and 25 is very good. I used Fedora 24/25 10 hrs a day for 3 months with hardly a single issue. Then I tried RHEL 7.3 for the past two weeks. Very disappointing. Barely usable. I would also like to point out that Intel makes a driver update tool for Fedora 24. I used it with good success. Not sure if they're supporting Fedora 25 with the update tool yet.
