The T150 uses a wide-screen LCD with an actual resolution of 1280x768, very similar to the TR2/TR3 series notebooks. Unfortunately, at the moment it is only possible to get 1024x768 graphics working automatically. This is not the fault of Xorg or Linux- the reason is that the video bios does not contain information about that mode. As you might expect, this means there will be dead areas on the left and right of the wide screen. You can “stretch” the screen in the BIOS, though, although the results are less than impressive. There is a utility called “855resolution” which, on many Intel 855 chipset laptops, will enable the user to replace one of the video bios modes with the timings for the 1280x768. It is reported to work on the TR2/TR3 machines, and several non-Sony wide-screen laptops and does work on the T150 but you have to move from the X virtual terminal to a text screen, then BACK to X. When that is done, the “scrambled” display “fixes” itself. To automate the 855resolution, I just tacked on the following script to the bottom of /etc/rc.d/rc.sysinit:
The script contains this:
855resolution 52 1280 768 > /dev/null
855resolution 43 1280 768 > /dev/null
This will replace both the 16bit and 24(32)bit color 800x600 resolutions with the new 1280x768. Then add this to your XF86Config monitor section:
HorizSync 20 - 90
VertRefresh 50 - 100
DisplaySize 230 138
Modeline "1280x768" 80.14 1280 1344 1480 1680 768 769 772 795
Note that the widescreen will not come back properly after a hibernate. The screen will be corrupt. Changing to a vt then back to X is not enough to fix it. Instead, you have to run the 855 script again and THEN change from a vt and back to X. Still looking for a way to automate that, but nothing I try works.
Note that when you use the wide display modes, it will corrupt the graphical-based VT consoles (not X). For this reason, you will need to modify /etc/lilo.conf and change “vga=768” to be “vga=normal” and rerun the lilo command. Bootups will be text-only, no pretty graphics, but it allows you to actually use the consoles.
这是在 Linux on Laptops 找到的配制信息。 但是我还是弄 不好. 能够详细点介绍如何 修改 这个 xorg.conf 么? 谢谢了. |
