Red Hat Bugzilla – Bug 198041
Resolution and timing mismatch
Last modified: 2007-11-30 17:11:36 EST
Description of problem:
The new i810 driver properly recognizes the native resolution of the MacBook LCD
panel (1280x800). xrander shows that is X is running at 1280x800 but the image
is not as sharp as it should be. Xvidtune shows that X is actually running at
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start X in 1280x800
1280x800 is properly selected but the image is not sharp (fonts are blurred).
xvidtune shows X is running at 1280x768.
Running @ 1280x800 resolution and timing.
This is on a Apple MacBook.

I found out that X is really running at 1280x768 instead of the proclaimed
1280x800. I can scroll the entire screen up and down a few lines (i.e. 800-768
lines). After I re-added my custom ModeLine:
ModeLine "1280x800" 71.0 1280 1328 1360 1440 800 803 809 823 -hsync -vsync
I have my 1280x800 back. This modelines is actually suggested by the driver:
(II) I810(0): Supported additional Video Mode:
(II) I810(0): clock: 71.0 MHz Image Size: 286 x 179 mm
(II) I810(0): h_active: 1280 h_sync: 1328 h_sync_end 1360 h_blank_end 1440
(II) I810(0): v_active: 800 v_sync: 803 v_sync_end 809 v_blanking: 823 v_border: 0
(II) I810(0): B133EW01 V0
(II) I810(0): Monitor name: Color LCD
This bug is fixed, for my MacBook at least. No 1280x800 modeline in xorg.conf
