[Desktop-packages] [Bug 1923513] Re: xrandr --panning problem
Thank you for the time & effort shown in researching the issue you've experienced. Before the bug can really be accepted & worked on by Ubuntu, it'll need to be confirmed that Linux Mint run-time adjustments are not-at-play, ie. confirmation on a pure Ubuntu system (with logs provided). Your logic & effort at finding your issue is noticed & appreciated. FYI: For best results, it's best to work on the current development release (so extra SRU steps aren't required, which currently are required for hirsute, so it'll be likely mean the next i-cycle). ** Changed in: xorg (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1923513 Title: xrandr --panning problem Status in xorg package in Ubuntu: New Bug description: Dear community Recently I upgraded my old netbook from Linux from Linux Mint 18 to Linux Mint 20 Distribution: cat /etc/upstream-release/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=20.04 DISTRIB_CODENAME=focal DISTRIB_DESCRIPTION="Ubuntu Focal Fossa" Netbook is with small screen 1024x600 To get bigger virtual screen I use xrandr like: xrandr --fb 1024x768 --output LVDS1 --panning 1024x768 To return to normal screen I use xrandr --fb 1024x600 What is expected: when the mouse moves outside the 1024x600 screen - new "clean" virtual area appears.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command only once, as it will automatically gather debugging information, in a terminal: apport-collect 1923513 When reporting bugs in the future please use apport by using 'ubuntu- bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs. Please note: `ubuntu-bug`, `apport` & bug reporting tools are provided with Ubuntu by default, many require manual addition for some releases of downstream OSes based on Ubuntu (eg. Linux Mint). You should check with your distribution first. ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1923513 Title: xrandr --panning problem Status in xorg package in Ubuntu: Incomplete Bug description: Dear community Recently I upgraded my old netbook from Linux from Linux Mint 18 to Linux Mint 20 Distribution: cat /etc/upstream-release/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=20.04 DISTRIB_CODENAME=focal DISTRIB_DESCRIPTION="Ubuntu Focal Fossa" Netbook is with small screen 1024x600 To get bigger virtual screen I use xrandr like: xrandr --fb 1024x768 --output LVDS1 --panning 1024x768 To return to normal screen I use xrandr --fb 1024x600 What is expected: when the mouse moves outside the 1024x600 screen - new "clean" virtual area appears.
