[Bug 1606103] Re: modeset driver does not detect all screen resolutions
Thanks Rocko (my fellow Perthian?). It seems you're right the modeset driver is just not /inventing/ the fake modes you desire. ** Changed in: linux (Ubuntu) Status: Incomplete => Invalid ** Changed in: xorg-server (Ubuntu) Status: Incomplete => Confirmed ** Summary changed: - modeset driver does not detect all screen resolutions + modeset driver is missing some fake modes that the intel driver had ** Summary changed: - modeset driver is missing some fake modes that the intel driver had + modeset driver is missing some modes that the intel driver had ** Changed in: xorg-server (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1606103 Title: modeset driver is missing some modes that the intel driver had To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1606103/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The output is the same for the 4.7.0 kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1606103 Title: modeset driver does not detect all screen resolutions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1606103/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This is the output for kernel 4.6.4-040604-generic (running back on Ubuntu 16.04, but I guess that shouldn't make any difference if we're just reading the kernel info): /sys/class/drm/card0-eDP-1/modes:3840x2160 (There's a bunch of other modes but they are all for the various resolutions on the HDMI screen). So it looks like it's just seeing one mode for the laptop screen, the native resolution. Does that mean it's inventing a bunch of modes anyway - just not the right ones? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1606103 Title: modeset driver does not detect all screen resolutions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1606103/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1606103] Re: modeset driver does not detect all screen resolutions
This bug might need reassigning to the kernel instead. I'm guessing that (like Mir) the mode-setting driver doesn't invent in- between modes like Xorg drivers do (and like legacy VGA BIOS's do for old CRTs) Please run this command to see if the kernel is the one failing to report those modes: grep . /sys/class/drm/*/modes ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1606103 Title: modeset driver does not detect all screen resolutions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1606103/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

To clarify my comment about 'ubuntu-bug xorg-server' not working, I had to do 'ubuntu-bug xorg-server-source', although it seems to have actually reported it against xorg-server in the end. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1606103 Title: modeset driver does not detect all screen resolutions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1606103/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
