Hi everyone, I’m a new user of Fedora (switching from Ubuntu for some adventure haha) and I’ve just finished installation of Fedora 34 a few days ago. I have a few questions about various things after installation. I don’t know if it’s better to separate them or put them into one post but for this time I’ll just list them here Sorry if this is not a good way to place the questions.
- I tried to tweak with my GRUB settings by following the [GRUB 2 - Fedora Project Wiki](official documentation). I’ve added a few kernel parameters for VFIO and also set the GRUB screen resolution using
/etc/default/grub, and then update the settings using
grub2-mkconfig -o /boot/grub2/grub.cfg. However, the updated kernel parameters are correctly reflected in
gfxmodedoes not appear in that file. What could this be caused by?
- I used the KDE spin of Fedora. For some reason the X11 version of Plasma does not work well so I used the Wayland version, and I used the X11 version of Plasma before. Everything works well, except for the blurriness for apps running in X11 using XWayland. I use a HiDPI screen with 175% scaling, and it seems XWayland support fractional scaling by directly scaling up the window rendered in smaller size. (Does XWayland support integer scaling correctly? I don’t know about that.) Some of these apps support fractional scaling well under X11, so I wonder if it is possible to let XWayland display these apps in a non-blurry way.
- In the new version of Dolphin included in Fedora 34 a single click directly opens a file or a directory. Is there any way to change the behavior to the regular “single click selects a file, double click opens a file” mode?
The content of my
/etc/default/grub file is listed below:
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora_ytliu-tp-t480s/root rhgb quiet"
GRUB_CMDLINE_LINUX_DEFAULT="splash intel_iommu=on iommu=pt rd.driver.pre=vfio_pci vfio-pci.ids=10de:1d12 i915.enable_guc=0 i915.enable_gvt=1"
