i can observe no fractional scaling on a default installation dell xps5790 even with a single monitor (4k). Connecting a second monitor the scaling is not working separately either. The most obvious effect is that the right side (top bar) goes off screen. I tried scaling with different display resolution to no avail.
I eventually started just using a lower display resolution and gave up on fractional scaling. nvidia 450 libmutter-6-0: Installed: 3.36.6-1ubuntu0.20.04.2 -------- xrandr program version 1.5.0 Server reports RandR version 1.6 ------------ lspci 00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Mobile) (rev 02) (prog-if 00 [VGA controller]) DeviceName: Onboard IGD Subsystem: Dell UHD Graphics 630 (Mobile) Flags: bus master, fast devsel, latency 0, IRQ 176 Memory at eb000000 (64-bit, non-prefetchable) [size=16M] Memory at 80000000 (64-bit, prefetchable) [size=256M] I/O ports at 4000 [size=64] Expansion ROM at 000c0000 [virtual] [disabled] [size=128K] Capabilities: <access denied> Kernel driver in use: i915 Kernel modules: i915 I found the prime-select toggle and set it to intel... same issue ** Attachment added: "xrandr --verbose #during broken scaling" https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1857383/+attachment/5431932/+files/xrandr.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1857383 Title: Fractional scaling applies to both monitors when you only want it on one To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1857383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
