OpenMandriva Lx version:
Desktop environment (KDE, LXQT…):
Description of the issue (screenshots if relevant):
Cannot set the display resolution to 1600x900
Relevant informations (hardware involved, software version, logs or output…):
I have installed additionally spice-vdagent.
Display is spice-server, video is Virtio, 3D acceleration enabled.
If I set the resolution to 1600x900 in Systemsettings -> Display and Monitor, it always stalls at 1024x768. Hardware is a Sony Vaio E series notebook with 17’ screen. It works well with other distros e.g. Mageia and Fedora.
Btw. I am a bit jealous that you have made the transitions I want to see in Mageia: dnf and NetworkManager.
Welcome @Bequimao to OpenMandriva forum and the OM distro. We hope you enjoy your time spent here and with OM Lx.
Post-edit: Unfortunatly I’m not much help for your issue. OM officially supports running OM Lx in VirtualBox only. We do have developers that use Qemu and I suspect we will hear from one when they get some time and see this. Being a small group and all volunteer we do the best we can at helping users.
maybe this will help you
Thanks for the link. I tested QXL video and didn’t see any difference. The default memory of 16 MB should be sufficient - my own calculation. 1600 x 900 isn’t exactly high resolution. The default memory is not shown, host is Virt-Manager on openSUSE 15.1.
I found another one (German)
I modified /etc/default/grub
The resolution of the virtual console is now at 1600x900, but the display still stucks as if hardcoded.
The cursor gets caught. Message is "Press Ctrl_L and Alt_L to release … That is quite annoying. This shortcut locks the screen under System settings -> Desktop behaviour -> Screen locking. After disabling it is still valid in other applications, e.g. konsole.
QXL: driver, kernel module qxl
Virtio : driver, kernel module virtio-pc
xrandr --output Virtual-1 --mode 1600x900
both cases: Configure crtc 0 failed.
My findings so far
spice-vdagent was installed, but not running.
In order to start it, I had to do the following steps:
# systemctl enable spice-vdagentd.service
d /run/spice-vdagentd 0755 root root -
Add 2 devices in Virt-Manager
- Channel spice
- Channel qemu-ga
It helps a lot to have spice-vdagentd running. But unfortunately the screen resolution problem is not yet solved.
spice-vdagent-0.12.0-9 is a tad outdated. As Openmandriva 4.0 is a fresh release, I would have expected version 0.19. It might be a security issue, too.
Retested. Screen resolution 1600x900 works now with upgraded Openmandriva 4.1.
Good to here from you @Bequimao. And thanks for letting us know. It helps.
