Title: Monitor screen brightness issues
Post by: gocool on February 27, 2013, 09:05:23 PM

Hi,
I am having issues with my desktop resolution, I had this issue before with my laptop and when I did an xsetup I could choose from the options available and it fixed it.

But here..

I get only one option and that is 640x480x16

But when I did a head -1 ~/.xsession
it shows the current resolution as 1024x760x32 but the screen is very dim, as if the brightness of the monitor has been turned below.

Not sure if I made myself clear, but the bottom line being my screen's brightness is way too low
(and yes the physical brightness of the monitor has been turned way up)

Any help will be highly appreciated.

Regards,
gocool

I seem to recall having a similar problem once about a year ago and I finally did get it to work right... but I don't remember how.  I remember trying a lower resolution, a lower color resolution and additional graphics related extensions, just not which  (or which combination) did the trick.... Yeah, and I don't remember for sure what PC I was using then either.  I'll try to wake up a few more brain cells.

What make and model of PC are you using and what graphics hardware?

Thank you Lee for your response.
Mine is a very old Dell Dimension 2400 Desktop all I know is that it is an Intel Pentium 4 wtih 256mb ram with around 80gb hdd. The video controller is a Integrated Intel 3D Extreme Graphics.

I think the system on which I had the issue was a Dell Dimension 4600 with similar CPU and memory and integrated graphics described by lspci as

    VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)

I'll see if I can check that system - but probably won't be able to until next week.

Poking in the mist... perhaps try load 915resolution.tcz?

Intel graphics + bad bios by Dell. Use Xorg.

On my Dimension 4600, with graphics-3.0.21-tinycore.tcz  loaded,

  Xvesa would only allow 640x480 and that was positioned too high on the screen to see the jwm tray.

  Xorg-7.5 allowed higher resolution (1152×864, I think) and it was properly positioned.

Neither had the brightness problem.

Without graphics-3.0.21-tinycore.tcz loaded,

  Xvesa behaves as described above

  Xorg-7.5 fails ("could not open display")


So I guess this was not the system where I had the dim screen issue.  Sorry for the noise.

No problem Lee, thanx again for trying.

Curaga, I am trying to install xorg over xvesa as per the wiki link below
http://wiki.tinycorelinux.net/wiki:using_xorg_over_xvesa

But when I go to the prompt and give the command "install Xorg-7.4.tcz", it just prompt me back with the help for install. I am sure there must be some switch or something to be given.

I searched for the file Xorg-7.4.tcz  which was downloaded under the ./tce/optional path so I tried it by giving the full path still the same issue.

What am I doing wrong?

Code: [Select]

tce-load -i Xorg-7.4.tcz
