|0005803||Kali Linux||General Bug||public||2019-11-21 01:12||2021-07-10 00:51|
|Fixed in Version||2021.2|
|Summary||0005803: HiDpi support|
Booted on a high rez system in live mode, Kali is not very usable as everything is so small. A "xrandr -s 1920x1080" in a terminal can be used as a work around, but we will need to automate this so as to allow for easier use for general users. Going to become more and more of an issue as super high rez displays become more common.
hello, it seems to me that we can edit "TAB" and send a grub or syslinux a "vga = 893" (see the VESA_BIOS_Extensions correspondence table) for the live / initrd.img https://en.wikipedia.org / wiki / VESA_BIOS_Extensions

I guess you have the same issue in non-live mode, i.e. if you install the system. This is really a problem that should be handled by the various desktops and not by us Kali.
It seems that GNOME has automatic support for this:
But Xfce doesn't seem to have anything automatic and it seems to be painful to configure:
So yeah, downgrading the resolution might be the easier approach.
Still I want to know. On a fresh live boot, what do you get as output for "xrandr" ?
Does "xrandr --dpi 196" gives a good result?
Does "xrandr --output XXX --scale 0.5x0.5" gives a good result?
I have read about "slick-greeter" supporting HiDPI. Maybe we should try to use it on a HiDPI screen and see if the sessions started through it behave better... I don't have any HiDPI screen to test anything though.
Screen 0: minimum 320 x 200, current 3840 x 2160, maximum 16384 x 16384
xrandr --dpi 196 does help, and "xrandr --output XXX --scale 0.5x0.5" works as well however things do start to look "fuzzy" across the board and the cursors get oversized.
Arch has a good guide at https://wiki.archlinux.org/index.php/HiDPI and for XFCE 4.14 does have better HIDPI support however when we change the scaling to 2x it does not impact all apps, most notably the terminal. Running "xrandr --dpi 196" combined with the XFCE change makes things usable (not perfect, but acceptable).
It seems like we could use an automated way of setting the xrandr dpi when on a hidpi display?
We have kali-hidpi as workaround now, closing this ticket.
