[opensuse-support] kernel vs. nouveau bug? report where?
I had the following bug report ready to submit, but I checked Fedora 38, and same problem there. Original Summary: absent both plymouth, and video= on linu lines, vtty[1-6] framebuffers produce vast raster right and bottom borders on the larger resolution of two displays To reproduce: 1-connect two unequal native resolution displays to a Tesla or Firmi GPU 2-don't have plymouth in use (I don't ever have it installed, so don't know whether it impacts) 3-don't include e.g. video=1440x900@60 directive on Grub's linu lines 4-boot TW 5-switch to a vtty, e.g. Ctrl-Alt-F3 Actual behavior: 1-Both displays utilize the resolution (same pixel grid) of the lower resolution display 2-Lower resolution display behaves as expected (light text on black background) 3-Higher resolution display uses same pixels as lower resolution display, with light text on black background, leaving right side and bottom raster instead of black Expected behavior: 1-Both displays utilize the resolution (same pixel grid) of the lower resolution display 2-Lower resolution display behaves as expected 3-Entire higher resolution display's background is black instead of portions in raster Workaround: add e.g. video=1440x900@60 to Grub's linu lines, which causes both displays to use the same nominal mode on the full display space. Typical other linu line options: noresume consoleblank=0 net.ifnames=0 ipv6.disable=1 preempt=full mitigations=none My Tesla has HDMI and DVI outputs, tested with 1920x1200 and 1680x1050 displays. My Fermi has dual DisplayPort, tested with 2560x1440 and 1680x1050 displays. Occurs with 6.3.2 and 6.2.12 kernel-default, *and* with 6.2.15 on Fedora 38. Does not occur with 6.1.12 kernel-default on NVidia, or with AMD Caicos (Terascale2) GPU, or with Intel Eaglelake GPU. Tested only on legacy booting (no UEFI support). Others might describe what I call "raster" as multicolored snow. Is there a Nouveau bug tracker to take this to, or does it need to goto bugzilla.kernel.org, or ??? Should I submit the report on BOO anyway? -- Evolution as taught in public schools is, like religion, based on faith, not based on science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks!
