Subject: [gentoo-user] xorg i810/i915 mode problem (modular X)
Date: Wed, 17 May 2006 06:18:20
Message-Id: 1147846327.29858.59.camel@localhost
1 I have a new Sony Vaio laptop with a 1366x768 screen using the intel
2 "Mobile 915GM/GMS/910GML Express Graphics Controller" which can be
3 driven by the xorg i810 driver. Works fine on the laptop in this
4 resolution.
5
6 The problem I have is that many of the possible modes for this chipset
7 return blank when xorg starts as in the example below from the xorg log
8 - the mode I want to use is 1280x1024 for an external projector.
9
10 I have (once!) been able to get 1280x1024 using 915resolution to force
11 the mode, and two screens but I need to use clone mode so this wasnt
12 practical (I want clone mode with the same desktop on both screens)
13
14 Can someone point me towards a solution please. It seems to me that
15 xorg is not reading the chipset correctly. Note that ddc on or off
16 doesnt help (and if I have an external monitor attached when xorg
17 starts, it really stuffs things up, also ddc on or off!)
18
19 My requirement is to use 1360x768 when standalone, or 1280x1024 on
20 either an LCD desk monitor, or same resolution on a projector in clone
21 mode. When doing the external thing, the laptop screen doesnt have to
22 be 'perfect'. Currently I can do this, but only in 1024x768, which
23 looks terrible on the ext LCD due to aliasing.
