Fedora 26 & 27 are unable to boot with normal graphic mode on this PC with AMD/ATI RS740 [Radeon 2100] GPU
5:58 a.m.
Hello, I have an old PC from 2008 which has integrated graphics processors (IGP), I did
install Fedora 26 few months ago and it had mentioned problem, I used
"nomodeset" kernel parameter for boot during installation and local boot, but I
didn't report the problem.
Today I did install Fedora 27 (Fedora-Workstation-Live-x86_64-27-1.6) and same problem was
exist, fortunately Fedora 27 is smarter and it added "nomodeset" kernel
parameter to the GRUB configuration file for local boot, so there is no need to enter it
manually to GRUB.

$ lspci | grep VGA

Please guide me step-by-step to solve this problem, thank you.

It isn't clear to me from your description what your problem is. Is
there no video? Is the video at the wrong resolution? Does X (or
wayland) fail to start? If your system is using the radeon driver from
the kernel, I think that is the best that the kernel provides for older
radeon hardware. There is an amdgpu module for newer hardware.
wayland might not support older hardware. In X, you will need to be
sure that the correct xorg-X11-driver package is installed,
xorg-x11-drv-ati.
What does lsmod show for the module the kernel is using?
What shows in /var/log/Xorg.0.log?
Can you successfully boot into multiuser (runlevel 3)? When the grub
menu comes up, you can hit a key and edit the kernel option line to add
a 3 to the end of it to boot into multiuser. If you can, what happens
if you then run the command startx?

I have video output, but when `nomodeset' parameter is used, xorg and
wayland use VESA resolutions, there is no full and complete resolutions
and also hardware acceleration, this is the problem. Both xorg and
Wayland sessions can be run via GDM, there is no problem in here.
wayland might not support older hardware.
Wayland works very well on this PC.

Yes, I did add "3" to the end of the line that begins with "linux"
and
removed "nomodeset" parameter to boot as normal, see the line "Kernel
command line"
If you can, what happens if you then run the command startx?
log-in as normal user and then:

The radeon driver is not being loaded by the kernel. It has support
for your card, from what I can find online. This is what is causing
your lack of hardware support. I run the radeon driver and when I do
lsmod | grep -i radeon
I get
radeon 1552384 12

The X module for radeon shows support for the RS740 (your card).
> Can you successfully boot into multiuser (runlevel 3)?
Yes, I did add "3" to the end of the line that begins with "linux"
and
removed "nomodeset" parameter to boot as normal, see the line "Kernel
command line"
Could you try doing a
dnf distro-sync
as root from runlevel 3, just to be sure no cruft was left around from
the upgrade to F27. I notice that your X was compiled on F26, and it
should have updated to an F27 version, I think.
After that, try rebooting with the nomodeset gone from the kernel
line. I think it is adding nomodeset because the radeon driver is not
loading. Could you show the kernel settings line?
What is the resolution on the virtual console when you boot into
runlevel 3?
Until the kernel loads the radeon module at startup, your video card is
not going to work properly. Something is preventing it from doing
that. If you type the command
journalctl -b
and look through the output, do you see any error when the kernel tries
to load the radeon module? What does the negotiation look like for
video?

Yes I could, but there was 900-1000 MB data for full upgrade! I did
remove some packages which I don't use them like "libreoffice**",
"qt**", 'cheese', gnome-boxes, totem, rhythmbox and even firefox, this
reduced size of upgrade to 500-600 MB, but because there is no guaranty
after download all of them my problem be solved, I didn't upgrade.
Instead of upgrade, I did install LightDM, then stop-disable
gdm.service and enable lightdm.service, then I did boot Fedora without
"nomodeset" kernel parameter and the result was LightDM ran on the
highest resolution supported by the monitor, 1920x1080, but like the
past, none of the available sessions can't start, I did reboot again
without "nomodeset" and log-in as normal user in one TTY then `startx'
the below log is for this:

Could you show the kernel settings line?
you can see them in log files in the line begins with "Kernel command

".... ro nomodeset rhgb quiet LANG=en_US.UTF-8"
What is the resolution on the virtual console when you boot into
runlevel 3?
the highest resolution supported by the monitor, 1920x1080

do

yes, there was some lines in the red color when I boot Fedora with
"nomodeset" but there was no red colored lines when boot without
'nomodeset' and even run the command `startx' as root:
<>
[drm:radeon_init [radeon]] *ERROR* No UMS support in radeon module!
.....

This seems strange
RADEON(0): Setting screen physical size to 508 x 285
but everything else looks good right up until you switch back to a
virtual console. So, I think there is an error in the startup of the
gnome desktop you are using. Can you try another desktop? The lightest
weight desktop available is LXDE, so it wouldn't take a lot of
installs. And, because it is so simple, it is likely to be less
affected by any conflicts that are affecting your gnome desktop.
I think there is also a way to tell Gnome to run X instead of wayland
from the desktop manager. Have you tried that?
When the desktop fails to start, and you switch to a virtual console,
if you run journalctl -r (reverse) there should be an indication of what
went wrong with the desktop startup also.
Here's another method. Boot into runlevel 3. Then run the commands
below in your home directory. This boots Gnome directly into X. The
advantage here is that the errors will display in the terminal if Gnome
fails to start.
echo '#! /bin/bash' > $XCLIENTS
echo ' ' >> $XCLIENTS
chmod +x $XCLIENTS
echo 'GSESSION="$(type -p gnome-session)"' >> $XCLIENTS
echo 'exec $GSESSION' >> $XCLIENTS
startx
you can see them in log files in the line begins with "Kernel
command
line"
".... ro nomodeset rhgb quiet LANG=en_US.UTF-8"
If this were a kernel problem, it might be worthwhile to remove quiet,
but for the actual issue this line is fine (you might want to
permanently remove the nomodeset, though, since your card supports
modeset).

the highest resolution supported by the monitor, 1920x1080
Your kernel and driver are just fine. You can confirm by running
lsmod | grep radeon
and seeing radeon show up.

So, I think there is an error in the startup of the gnome desktop you
are using.
Yes, I did run `journalctl -r' and there was many errors related to
"gnome-shell" also in the graphical environment I did run gnome-abrt
("Problem reporting" applicatin) and there was the same crash report, so I did
report it.
Can you try another desktop?
Yes after exprience of LightDM I myself had the idea to install a light-weight desktop to
see what will happens, my choice is XFCE, I did install it and it runs without any
problem! :)
I think there is also a way to tell Gnome to run X instead of wayland
from the desktop manager. Have you tried that?
Yes, I did try all of them before. "... none of the available sessions can't
start ..."
Well, thank you for answer to this thread, I hope this problem be solved for next release.
