Bugzilla – Bug 904417
Gnome does not start because both ati and intel cards are active at the same time
Last modified: 2015-02-19 02:46:25 UTC
I have a laptop with an ATI and an intel i915 video cards. GDM refuses to start and Gnome (when started using xdm) fails to start because "something bad happened". Looking at the system logs I noticed both the video cards are enabled, I googled a bit and I found: * https://bugzilla.redhat.com/show_bug.cgi?id=896400 * http://dummdida.tumblr.com/post/83701431934/i915-and-radeon-both-enabled-on-vgaswitcheroo-at-boot I added the "radeon.modeset=0 radeon.dpm=1 radeon.aspm=1 radeon.runpm=1" to my kernel options and everything now works fine. This is a regression, everything worked fine with openSUSE 13.1
GNOME is only the messenger - the 3D Modes don't work, it can't do much. Considering that you have to pass kernel parameters, I guess kernel is as good a start as it gets.
More likely an X problem unless the system really crashes :) In anyway, please give the hwinfo output, kernel messages at failure, and more importantly, Xorg log. (I heard from Stefan that gdm no longer records /var/log/Xorg.0.log. In that case, give the relevant journal output, too.)

Ping me if you need more information/tests.
Thanks. So, your machine is the switchable GPU, not the hybird graphics? I quickly tested a machine with hybrid graphics (Intel + AMD), and it works fine with GNOME. But, it's a hybrid graphics, and the story is completely different if it's about a switchable graphics. Looking at X log, there is no error or crash trace found there. And it shows that both AMD and Intel have the all outputs (LVDS, HDMI and VGA). Maybe it confused GNOME. Try to look though all journalctl output whether you can find the trace of GNOME crash. Also, try to install xdm and twm, switch to xdm (via /etc/sysconfig/displaymanager) and login to twm. If you can login, you can play better there. Get xrandr --verbose output to see which outputs are actually detected / active.
BTW, you should be able to toggle the VGA switcheroo, e.g. put something like below in /usr/lib/systemd/system/switchable-graphics.service: [Unit] Description=Set up switchable graphics Wants=remote-fs.target After=systemd-modules-load.service Before=display-manager.service ConditionPathIsReadWrite=/sys/kernel/debug/vgaswitcheroo/switch [Service] Type=oneshot # can be either OFF, IGD, or DIS ExecStart=/bin/bash -c "echo IGD > /sys/kernel/debug/vgaswitcheroo/switch" ExecStart=/bin/bash -c "echo OFF > /sys/kernel/debug/vgaswitcheroo/switch" [Install] WantedBy=graphical.target Then enable it via "systemctl enable switchable-graphics.service" and reboot. The example above switches to Intel graphics and tunrs off the unused GPU. If you want to use AMD graphics instead, replace "IGD" with "DIS". Maybe we should package this somehow if this really works.

The BIOS does not allow me to do all the tuning I can do on another computer with a hybrid graphic. > Looking at X log, there is no error or crash trace found there.

The screen stays black or with the picture used by the initrd. Installing xdm/lightdm solves the gdb problem. However once I log into Gnome (via either xdm or lightdm) I get the "Gnome sad face". I'll try to reproduce that again. Xfce works fine.

As you will notice the ATI stuff is still found. I also tried to restart the display manager server but nothing changed.

Go to runlevel 3, and check the value in /sys/module/snd_hda_intel/parameters/power_save. To minimize the power save timeout, set it like echo 1 > /sys/module/snd_hda_intel/parameters/power_save Then wait for a few seconds, check the contents of /sys/class/sound/hwC?D?/power_off_acct files, and confirm that the values increase at each time you see them. If yes, all audio codecs have been powered off. Now, run "echo OFF > /sys/kernel/debug/vgaswitcheroo/switch", and retry starting GNOME.

OK, thanks. I forgot the recent changes of radeon dpm interfering the vgaswitcheroo... There have been a fix fixes related with radeon, vgaswitcheroo and ACPI in 3.17. Could you check whether 3.17 kernel works as is? It's available in OBS Kernel:stable repo.
I tried with the latest kernel, it didn't help :(
OK, thanks it's good to know. Meanwehil, I'm wondering whether it's really a kernel / 3D issue. What happens if you uninstall xf86-video-intel and xf86-video-ati but keep xf86-video-modesetting package? Then all 3D stuff will be gone and rendered in software via Mesa. Does GNOME still crash with it?
Also, could you give the output of "xrandr --verbose" when you login on icewm? I'd like to see which outputs are detected and active.
Similar situation here, neither up- nor downgrading the kernel helped. lightdm and XFCE work okay. lightdm with GNOME used to work (with external monitor?) but no longer does standalone ATM. # cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :DynOff:0000:01:00.0 2:DIS-Audio: :Off:0000:01:00.1 # lspci [...] 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 159b Flags: bus master, fast devsel, latency 0, IRQ 50 Memory at c0000000 (64-bit, non-prefetchable) [size=4M] Memory at b0000000 (64-bit, prefetchable) [size=256M] I/O ports at 4000 [size=64] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 2 Capabilities: [a4] PCI Advanced Features Kernel driver in use: i915 Kernel modules: i915 [...] 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

Confirming that deinstalling some xf86-video-* packages lets both gdm and GNOME work in my case: "Gallium 0.4 on llvmpipe (LLVM 3.5, 256 bits)" I also only have one monitor displayed in gnome-control-panel then, and LibreOffice Impress presents as expected this way.

Although it's not active, it's reported as connected (and doesn't show the proper attributes either).

That's good to hear at least. Could you give xrandr --verbose output on this, too? I'm interested in whether LVDS-1-1 status is different, depending on X driver.

Thanks. So, modesetting driver didn't take the inactive radeon. It explains why GNOME would work with this.
One more quick test. Could you install drm-kmp package found in OBS home:tiwai:bnc904417/radeon repo, reinstall xf86-video-intel and xf86-video-ati, and retest? (It would work only with LVDS, no other connections expected.)
Wait... Now I read radeon code more carefully and noticed that there is actually a module option radeon.runpm. Setting radeon.runpm=0 should disable PX, i.e. the hybrid graphics mode, and it'll allow again vga swticheroo as before. So, can anyone confirm this? Just boot with radeon.runpm=0. Do "echo OFF > /sys/kernel/debug/vgaswitcheroo/switch" or something like that appropriately if needed, then start GNOME.

OK, then we just need to disable PX for this kind of machines. There is a blacklist and we'd need to add the new entries there. Andreas, could you give hwinfo output from your machine? Also, Flavio, please check whether radeon.runpm=0 makes things working again on your machine, too.
A bit of status updates: - radeon.runpm=0 option would make the system behaving as before, so if you prefer the old days, you can still go this way as a falback. - I updated radeon-kmp package in OBS home:tiwai:bnc904417/radeon repo, and it contains the radeon module including a test fix from upstream. With this update, the radeon driver should show the outputs as disconnected unless the controller is activated via vgaswitcheroo, so that GNOME should be no longer confused. The latter method has basically more merit: the power can be turned on/off more dynamically while we may switch outputs more smoothly. So, please give radeon-kmp a try. If it works, I'll report back to upstream.
Ping...
(In reply to Takashi Iwai from comment #27) i | radeon-kmp-desktop | Paket | 3.16_k3.16.6_2-4.1 | x86_64 | OBS tiwai radeon With this kmp and radeon.runpm=0 still in the cmdline, gdm does not come up but instead the previous screen remains. The IGD is active, and both are powered. With the same sequence as before - rcxdm stop; echo DDIS > .../switch; rcxdm start - things still work. I'll try whether dropping that command line argument improves things next.
(In reply to Andreas Färber from comment #29) > I'll try whether dropping that command line argument improves things next. It does! It comes up on the IGD now: "Intel® Sandybridge Mobile" And only one monitor is detected in GNOME control center. andreas@envy:~> sudo cat /sys/kernel/debug/vgaswitcheroo/switch root's password: 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :DynOff:0000:01:00.0 2:DIS-Audio: :Off:0000:01:00.1

Let's close now.
Sorry for being silent on this issue. I have been traveling a lot lately and I didn't have this laptop with me. I'll check the fix once it's available in the updates channels.
