Qubes 3.2RC1: number of issues

[Dima Puntus]

Hi,

Here's the info:

System: HP Elitebook 2570p (3840QM, Intel HD4000, 16GB RAM, 250GB SSD)

Qubes 3.2RC1,

1. Dual monitor setup seems glitchy, by default the system mirrors the screens but if you force it via xrandr, the laptop screen goes black, can't right click on it but can drag windows into it and maximize. The panel always stays on the external monitor. Same setup using Qubes 3.1 works like a charm out of the box. There's no display/monitor section under system settings.

2. USB mouse (Razer Abyssus) sensitivity is too low by default and can't be adjusted via system settings. Works fine in Qubes 3.1 Trackpad is fine.

 

3. Dom0 is only seeing 3.8GB RAM. Is this by design? I can still allocate 10GB+ for individual VMs so the RAM must be visible by Xen. 

4. Sensors Viewer doesn't register max CPU temps when changing polling interval (I normally set it to 1-3sec). Same issue in Qubes 3.1

5. Plasma crashes when trying to change the default theme. That seems to be related to plasma 5.x as it crashes on every standalone linux machine for me including Kubuntu 16.04.

6. Question: is it possible to set max CPU threshold per VM? I can only set it for all 8 vcores using xenpm

Thank you and hope this info helps improving some rough edges in the new version.

Let me know if you have any questions.

Dimitry

It's by design. However, this same limit was already implemented at least
for 3.1 that uses 1-4GB dom0 memory depending on how much memory the
machine has. Is there some particular issue associated to this question
or you just noticed the limit?

IIRC, there's some parameter for this limit on some of the boot related
commandlines.

3 and 6 are just questions I guess.

 

Thank you

Yes, others have also reported this. It seems that there are some
missing packages in dom0. For now, you can work around this by
installing kscreen:

$ sudo qubes-dom0-update kscreen

This should make KDE recognize your external monitor. Then you should
be able to run kscreen like so:

$ kcmshell5 kscreen

(Thanks go to Micah Lee for providing these instructions.)

Hm, strange. Could this be a hardware compatibility issue with the
mouse? Can you test whether it works with baremetal Fedora 23?

It sounds like this might just be a limitation of the Sensor Viewer
applet. You may want to consider filing a report with whoever develops
it.

Might be worth filing a report with the KDE developers about this.

I probably have no idea, but may I ask what exactly you mean by
"threshold"? As in, speed? (You can adjust the number of VCPUs assigned
to a VM in the "Advanced" tab of the VM's settings in Qubes Manager.)
