Description of problem:
Latest xorg-x11-server uses modeset driver instead of intel.
I know this is planed for >=f26 but not on f25.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
[ 63.010] (==) Matched modesetting as autoconfigured driver 0
[ 63.010] (II) LoadModule: "modesetting"
[ 63.010] (II) Loading /usr/lib64/xorg/modules/drivers/modesetting_drv.so
[ 63.011] (II) Module modesetting: vendor="X.Org Foundation"
[ 63.024] (II) modesetting: Driver for Modesetting Kernel Drivers: kms
[ 63.025] (II) modeset(0): using drv /dev/dri/card0
[ 63.030] (II) modeset(0): Creating default Display subsection in Screen section
[ 63.030] (==) modeset(0): Depth 24, (==) framebuffer bpp 32
[ 63.030] (==) modeset(0): RGB weight 888
[ 63.030] (==) modeset(0): Default visual is TrueColor
[ 63.051] (II) modeset(0): glamor initialized
And, at least for new intel cpu's, the modesetting driver fails :
[114614.766] (II) Loading /usr/lib64/xorg/modules/libfb.so
[114614.767] (II) Module fb: vendor="X.Org Foundation"
[114614.767] compiled for 1.19.1, module version = 1.0.0
[114614.767] ABI class: X.Org ANSI C Emulation, version 0.4
[114614.768] (==) Depth 24 pixmap format is 32 bpp
[114614.768] (WW) glamor0: Failed to get GLSL version
[114614.768] (EE) modeset(0): Failed to initialize glamor at ScreenInit() time.
Fatal server error:
[114614.768] (EE) AddScreen/ScreenInit failed for driver 0
lspci -v | grep VGA
00:02.0 VGA compatible controller: Intel Corporation HD Graphics P530 (rev 06) (prog-if 00 [VGA controller])
filed a separate bug on modesetting failure :
This change makes some resolutions unavailable on my laptop with a 1920x1080 panel and Intel HD 4400.
After the upgrade all 16:9 resolutions (a part from 1920x1080) disappeared, like 1600x900 that sometime I use.
Downgrading to 1.19.0-0.3.20161026.fc25.x86_64 everything is working as expected.

JFTR , in Fedora 25 I'm tracing a long stand bug and seems xorg-x11-drv-intel-2.99.917-26.20160929.fc25.x86_64 is the problem , it some circumstances system slowdown a lot and is impossible to work, laptop gets very hot, processes take 100% of CPU and no explanation for that, after switch to modeset i.e. dnf remove xorg-x11-drv-intel . The laptop seems that get back to normal i.e. no processes taking 100% of CPU etc etc
Also sometimes I got a little screen corruption specially on "GTK+ applications in KDE" and seems is also xorg-x11-drv-intel fault this happen since F23 or so .
So in conclusion I would recommend revert the fix in this bug report, should I reopen this ticket ?
