On a BIOS boot (grub --target=i386-pc) with the same kernel the VESA BIOS mode 2560x1600 is available and will be used by grub so the aspect ratio is always 16:10. On a UEFI boot, the only mode grub reports as being available is 1920x1080 (which is letterboxed 16:9 aspect ratio) so it uses that and the kernel should properly switch to 16:10 aspect ratio for 2560x1600 mode.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
