Bug #196318 that I just filed has a description of what is happening and why the Virtual resolution works.
If you're bumping into a hardware limitation on the total framebuffer size, you will probably have to use xrandr to resize your LVDS output to make room for the external display in the giant fb shared by both outputs. I hope to have a patch to dynamically allocate the big fb when I have a chance to learn the code and make a patch (so it could be a while ;) That won't help if you're hitting a hardware limit, but it'll remove the need for the virtual workaround. The full solution would be multiple, dynamic fb allocations, but I don't know if or how that is possible atm. -- higher resolutions aren't recognized for external monitors after hotplugging but after X start [intel] https://bugs.launchpad.net/bugs/158415 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
