> I tried 0 and 1 for radon.new_pll, running sudo update-grub after each one. Both are still blurry. I should not have to reboot the machine or logout, right?
No - /etc/default/grub & update-grub change boot time options. You'll need to reboot after editing these options before they will take effect. While you're doing that, could you please add drm.debug=0x04 to the GRUB_CMDLINE_LINUX_DEFAULT line? That will add extra debugging information into your dmesg log. It would be useful to try with the KVM switch set to the this machine during boot, just to eliminate that as a possible source of confusion. It might also be useful to try different resolutions on the second monitor - perhaps one works, and that might help isolate a difference between a resolution that works and one that doesn't. Once you've set drm.debug=0x04, could you please attach the output of running “dmesg” after trying (and failing) to set 1920x1080 on the external monitor? That will have lots of data for debugging, some of which might help. -- system cannot display extended desktop on Samsung 2333sw https://bugs.launchpad.net/bugs/664646 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
