[SOLVED]KVM switch shuts off hdmi and vga after -Syu

WFV · 2015-06-10 00:40:50

My Arch pc is connected to a 4 port KVM switch so the keyboard and mouse is shared with two other pc's. The monitor is connected direct to the Arch pc via HDMI, the other two thur the KVM via VGA. When I was running Arch 3.17.41 I could switch back and forth between the pc's (and would only have to manually select VGA (defaults to HDMI) on the front of the monitor itself. Since having recently -Syu'd the system, I can switch away from the Arch pc but cannot switch back. The mouse and keyboard do switch but the monitor does not. Same thing if connected thru KVM via VGA. My thinking is that when I switch away from the Arch pc, a signal from the monitor tells the system the monitor is OFF? and something in Arch then shuts off the video ports? Since then did a complete system re-install, and KVM switching between the 3 pc's worked right up to enabling and starting the network (netctl and NetworkManager).

I edited this because it is not a KVM problem, I get the same results if I simply put monitor to sleep and wait for the monitor to display "HDMI signal not present" then try to wake it up with keyboard or mouse. I can CTRL+ALT+F to another tty, login as user and systemctl restart gdm and then it will kick back to the tty with the desktop and HDMI wakens.

Thank you

i don't have bluetooth or ir hardware so probably didnt need to install those with Pulse? temporary workaround, log out of Desktop Environment, the hdmi signal remains intact when KVM switching to other pc's and back

WFV · 2015-06-13 03:21:08

I admit and will file my disclaimer here as well, i did not read the how to ask questions in a long time however, all of my searches on the internet haven't revealed anything, closest information to possible KVM interfering with video switching all has to do with virtual machines (do not apply as my virtual machines switch without issue). This problem started with -Syu when i had 3 vbox instances - attempts to repair system ultimately crashed my O/S (db got corrupted somewhere) could not pacman anything so did a complete re-install without dd-ing the drive and problem recurred as mentioned at the beginning of this post and before i re-installed vbox. It is not a vbox problem, and i dont think necessarily a kvm problem as i can reproduce the same result simply by putting the monitor to sleep without switching to another computer via kvm - it does not wake up, have to switch to another tty and restart gdm (gdm-it!). Arch forum is last place i want to ask questions because i see that it is annoying to real programmers and compounds the community efforts to keep it simple (categorically) - so mostly i come here and look for answers without asking questions and without logging in, it is a last resort for me to ask here. I've been working on this since 5/26 everyday for 2 weeks before asking if anyone else have this problem in Arch.

<off-topic>

WFV, you could use the "edit" button a bit more (3 separate posts in 4 minutes is a bit much) but that's a minor issue.

Arch forum is last place i want to ask questions because i see that it is annoying to real programmers and compounds the community efforts to keep it simple (categorically)

Not sure what you mean by that, but i'm not a real programmer and am used to dealing with complicated issues.

i don't have bluetooth or ir hardware so probably didnt need to install those with Pulse?

correct.

Summary :
Your system has 1 AMD videocard and 2 sound outputs (analog & hdmi ).
For sound you use the analog output, for video you use the hdmi output of the videocard.
Sound is managed by Pulseaudio.

I don't know your DE, but since you use gdm it's likely gnome.

If you logout of DE , you have no problems with switching monitor through KVM .

If you are logged in in your DE :
when you use kvm to switch the monitor to another system OR the monitor goes to sleep
X isn't able to awake the monitor
Restarting gdm manually from console does awaken the monitor.

When the problem happens, Journal shows messages about hdmi speaker not being present.

Please verify if that's an accurate description.

Some additionial questions :

Are you using catalyst or radeon driver ?
Which DE are you using ?
If you disable gdm, boot to multi-user target and start your DE through startx , does the problem also occur ?
Does the problem also occur if you use another WM/DE ?

Thank You Lone_Wolf. I will try to do better here. real programmers, a better choice may be linux enthusiasts with a far greater comprehension of linux than i possess. I read the forums and Wiki's and often times find what looks like solutions to problems I'm trying to fix with my system but so much of it is implied that i realize these people know all the in between steps that i don't so its a steep learning curve for me - I mean no disrespect to Arch Community.
Ok you summed it up correctly overall. The mobo is Asus M5A88-M using its on-board AMD video (not pci video board). Same with audio, on-board + hdmi (my monitor doesn't have built-in speakers, it does have headphones jack but I'm unable to get sound out of them at present). I'm using Xfce DE (my prior system was also Xfce but without gdm, the lxdm package is in the old backups so i assume i was using lxdm before although i thought my son set it up to auto launch startx to Xfce DE without using any DM, is that possible?). Not sure what driver is being loaded as all of these were in the prior system so i installed them from the repos (not local backups) in the present system:

the problem existed before and after installing the above driver packages although these are newer versions of the the original drivers before OS crashed. Pacman.log during installs mentioned some additional work needed I'm sure i didn't complete because it had to do with intel or nvidia video drivers which i don't think apply. The onboard multimedia and a 5.25" bay multimedia (card-reader, external SATA port, additional USBs + mic and headphone ports) lists as AMD ATI, but are using intel drivers

If you disable gdm, boot to multi-user target and start your DE through startx , does the problem also occur ?

Not sure how to boot to multi-user, i thought my original grub had an option like that? grub now only shows grub and fallback.

Does the problem also occur if you use another WM/DE ?

I'm guessing I can disable gdm and enable slim which is also installed, then test from there?

Whats your kernel version? Is it: 4.0.5-1-ARCH?

If so try this command:

xrandr --output HDMI-0 --auto --set audio off

After this does KVM switching work as normal? (do not reboot after typing the command - if you reboot you need to run it again)

Kernel 4.0 gave me issues with HDMI out on an ATI card...
These all got fixed in Kernel 4.0.2 (or 4.0.3 I forget).
They then got reverted in Kernel 4.0.5 due to them breaking other stuff...

In short, you could try another pacman -Syu to get you up to 4.0.5, it may fix your problem. If it doesn't I am all out sorry !

The KVM switching problem does not exist in LXDM, but does if I power off the monitor with the monitor power switch, then power it back on. Problem is not a Keyboard-Video-Mouse switching problem as mentioned in the title ( unless the kvm switch is sending a signal to the Arch pc that is being misinterpreted in GDM? ), the same results happen from putting monitor to sleep in GDM without switching to other pc's via a kvm switch. I'm able to switch to other pc's via the kvm switch and I do not lose the hdmi or vga signal to monitor when switching back so long as I am in the LXDM DE, it also does not happen in GDM if I first log out and leave it at the GDM logon screen. I do not have to log out of LXDM when switching via KVM. I haven't tested putting monitor to sleep in LXDM. I set sleep, off, and blank to "never" and disabled "Handle display power management" in Xfce Power Manager gui when troubleshooting the problem in GDM but those made no difference in GDM.

If the problem is only in xfce, then it sounds similiar to this, which leads to: https://bugzilla.xfce.org/show_bug.cgi?id=11107.
You may want to perform step 2 to 7 from the first link, if only to rule out the possibility.

Read the links, thank you Tutti.
Ok, some of those steps are over my head, like testing from ssh and Byoub. I am convinced is same bug. I was able to switch via KVM using LXDM but when I turn off the monitor with the monitor power switch, and power it back on, no video. So yes Xfce4 problem - just strange that can use the KVM with LXDM and not GDM, but with the monitor power button video shuts off.

trying this patch https://forum.manjaro.org/index.php?topic=19411.0

so far is working with KVM switch and with monitor power button (its a downgrade version of Xfce4 with the patch in it to not shut off HDMI port), ran the wget-install and testing from there.

Thanks for pointing me to the bug-report Tutti, there are a lot of links to similar/same problems and different workarounds and tests - including the patch from Manjaro.

The fix works for the KVM switch and monitor power button, but looks like it interferes with USB devices in VirtualBox guests - none of them work after installing the older patched version of Xfce4-settings. Might also have impacted MediaTomb some, will do more research.

Syu broke the HDMI output again.

 # uname -a = Linux arch-bill 4.3.0-1-ck #1 SMP PREEMPT Sun Nov 15 12:30:25 EST 2015 x86_64 GNU/Linux

Downgraded xfce4-settings 4.12.0-3 to 4.11.3-3 (from the https://forum.manjaro.org/index.php?topic=19411.10;wap2) which didn't fix it either, followed directions but notice it looks like it loads all the pertinent files to /home/user/xfce4-settings. So I copied the xz file to ~/.pacman/pkg and ran pacman -U to the created package, but that didn't work either.
What's working now is I downloaded the 4.10.1-1-x86_64 from Arch archives, installed it but had to sym-link libxfce4util.so.7 libxfce4util.so.6 for xfce-settings-manager to launch. Launching it has some GLib critical errors, but its working and the HDMI port is staying connected.

(xfdesktop-settings:8165): GLib-GObject-CRITICAL **: g_value_get_uint: assertion 'G_VALUE_HOLDS_UINT (value)' failed

only applies to desktop background settings.

https://bugzilla.xfce.org/show_bug.cgi?id=11107

Solved by installing this patch.
xfce4-settings 4.12.0-3
