>From https://bugs.freedesktop.org/show_bug.cgi?id=97163#c15, I think it's just a matter of some modelines missing from the xf86DefaultModes array in xf86DefModeSet.c, eg I suspect that adding this:
/* 2560x1440 59.96 Hz (CVT 3.69M9) hsync: 89.52 kHz; pclk: 312.25 MHz */ {MODEPREFIX, 312250, 2560,2752,3024,3488,0, 1440,1443,1448,1493,0, V_NHSYNC | V_PVSYNC, MODESUFFIX}, will give me my missing 2560x1440 mode. My xserver builds but I still haven't figured out how to get it to run, so I can't test it. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1606103 Title: modeset driver is missing some modes that the intel driver (and Mir) has To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1606103/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
