This seems not wrong to me. I wonder what's the correct resolution provided by previous driver. This change may also be caused by xserver upgrade? Anyway you can set preferred mode in xorg.conf to make it work as you like. Let Ling to confirm. hi Paul I'm not clear what is your expected result? those connection status of your xrandr command are right. Xorg will chose the best mode line for VGA and LVDS, driver is only responsible to execute, not like driver's issue. Working with 2.6x is from result Xorg, not driver. Thanks Ma Ling Dear Ma Ling, thanks for your comment. (In reply to comment #2) > I'm not clear what is your expected result? The resolution of the LVDS should also with the VGA cable plugged in be the correct resolution, that is 800x480 and not smaller 640x480. > those connection status of your xrandr command are right. > Xorg will chose the best mode line for VGA and LVDS, driver is only responsible > to execute, not like driver's issue. > Working with 2.6x is from result Xorg, not driver. Ok, so I reassign to component *Other. Could you please tell me the correct component. Could the reason for this behavior be, that Xorg tries to choose the same aspect ratio for the LVDS and external/VGA monitor?

Seems likely. xf86InitialConfiguration tries to find a mode that's supported by all connected outputs at startup.

Exactly, xf86InitialConfiguration tries to find a mode that's compatible with LVDS and VGA, it is not driver issue. Thanks Ma Ling Dear Paul Because it is not bug, I close the issue. please open it if you need. Thanks Ma Ling |

Created attachment 25886 [details] log with the monitor connected and using xrandr to switch and set up displays Dear xorg-, intel-hackers, I think since version 2.7.0 and currently with 2.7.1 booting my ASUS Eee PC 701 4G the screen is too small with black line on the left and right (640x480). I do not use a xorg.conf. Using xrandr (--auto) afterwards sets up the size correctly (800x480). It used to be working before with 2.6.x. Here is the behavior. I did sudo invoke-rc.d gdm restart between the steps. ### Without monitor connected to VGA ### $ date && xrandr # no monitor Fr 15.
