This is with external monitor connected, which is DP (through USB-C dongle probably converting USB-C DP alternate mode to HDMI). Laptop screen is DSI. Additional details with laptop screen, Windows 10 detects an "active signal resolution" of 800x1280 but weirdly @ ~75 hz (which isn't included in the xrandr output). Sorry I won't be able to give more Windows 10 info as I nuked everything when I installed arch.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
