After doing this I found the reason for the different clock values: For linux 4.6 I get these lines: [drm:parse_lfp_panel_data] Found panel mode in BIOS VBT tables: [drm:drm_mode_debug_printmodeline] Modeline 0:"1600x900" 0 100400 1600 1648 1680 1792 900 902 907 932 0x8 0xa For linux 4.7 I get these lines: [drm:parse_lfp_panel_data] Found panel mode in BIOS VBT tables: [drm:drm_mode_debug_printmodeline] Modeline 0:"640x480" 0 25180 640 648 744 784 480 482 484 509 0x8 0xa I attached the beginning of both logs for further infos. So it seems the code that retrieves the available modes from the BIOS does something different between these 2 versions.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
