 How to add Xvesa modes? (for 1680 x 1050 screen) |
|
Hello,
(Puppy 2.16)
I recently got a new 1680 x 1050 screen which works nice from my notebook but the graphics in my little VIA EPIA-ML PC doesn't support that size.
In xorgwizard, the best that comes up for Xorg is 1280 x 1024 (which I think comes from the graphics chip) and it's badly stretched. (Actually 1680 x 1050 does come up, but it doesn't work)
My understanding is Xvesa doesn't use the graphics chip and just does it alone. In Xvesa the best mode 0x013E 1400 x 1050 which is not bad but it would be nice if I could get the full 1680 width.
Anyway my question is, is it possible to add a new mode to Xvesa? Or is there a way to switch off acceleration in Xorg and get the mode in that?
TIA
David

try this for xorg:
type:
xrandr
This should show something like this:
| Code: | # xrandr
Screen 0: minimum 400 x 300, current 1680 x 1050, maximum 1680 x 1050
default connected 1680x1050+0+0 0mm x 0mm
1680x1050 60.0*
1024x768 60.0
1400x1050 60.0
1280x1024 60.0
|
If you have luck, that works.
If xrandr does not work, try ddcprobe.
But that often fails with an error:
edidfail
So I use xrandr.
Important is to get the frequency for the desired resolution.
If it is 60.0, then type:
gtf 1680 1050 60.0
This will show something like this:
| Code: | # gtf 1680 1050 60.0
# 1680x1050 @ 60.00 Hz (GTF) hsync: 65.22 kHz; pclk: 147.14 MHz
Modeline "1680x1050_60.00" 147.14 1680 1784 1968 2256 1050 1051 1054 1087 -HSync +Vsync
|
Now edit /etc/X11/xorg.conf
In the
section "Monitor"
add those values from gtf.
Example:
| Code: | | Modeline "1680x1050" 147.14 1680 1784 1968 2256 1050 1051 1054 1087 -HSync +Vsync |
Note:
I replaced
"1680x1050_60.00"
with:
"1680x1050"
Also be shure to have in
Section "Screen"
the line:
Modes "1680x1050"

Thanks Mark
When I run from Xorg @ 1280x1024 I get

Ran gtf on the only 1680 in all of that ...
| Code: | sh-3.00# gtf 1680 1050 77

Modeline "1680x1050_77.00" 193.27 1680 1800 1984 2288 1050 1051 1054 1097 -HSync +Vsync
|
Added
| Code: |
Modeline "1680x1050" 193.27 1680 1800 1984 2288 1050 1051 1054 1097 -HSync +Vsync
to [Monitiors]
and
Modes "1650x1050"
to [Screen]
|
But Xorg still didn't like it, it wouldn't start and I had to cut the power.
Any suggestions? Thanks David

Typo-error, or you have that in your conf?
must be 80.

Using puppy 301
I have this
DESCRIPTION: Intel Corporation 82946GZ/GL Integrated Graphics Controller
VENDOR: 8086 DEVICE: 2972 KERNEL MODULE: unknown
and
Acer x193p widescreen monitor.
The monitor's maximum resolution is 1440x900 which is available in the xorg wizard (at 24 bit) but produces a significantly blurred image - not usueless but impractical. I think some frequency is wrong. Vertical lines are worst affected. I've tried the tweek button. The strings '82946' and '946' produced no relevant help in a search of this forum. I've run randr and gtf and edited xorg.conf as advised at this thread and
http://www.murga-linux.com/puppy/viewtopic.php?t=15515
1440x900x24 is also xvesa wizard but has the same fault. If I boot ms can I get the settings from there somehow? Any advice as to how to get it working?
