I have a TV that supports 1360x768 resolution. It was not detected in Gentoo. I am currently using Ubuntu, and it detects lots of resolutions including 1360x768. Also, I messed ...

[SOLVED] HDMI resolution
Anyways, I used xrandr newmode and addmode, but the TV said that the resolution was invalid. Would anyone please tell me what I need to do to get 1360x768 resolution detected without adding custom modelines? I would use modlines if that is not possible, but I want it to detect the resolution automatically.
Sorry if that sounds silly.
Thank you very much.

Are you using a NVIDIA video card and drivers?
If not, what are you using? I believe this information would help a lot.

OK, so let me get this correct, you want you ubuntu to detect your resolution or Gentoo?
Hopefully ubuntu cause thats what I'm more familiar with, but anyways...
And so you said it detected 1360x768? But it's not applying it, or what? Do you get it to display, just a weird output/display? And are you using dual monitors, or one? (Cause I would imagine it would be hard to set the settings for another monitor by using a smaller one, then switching back and forth )
Heres some ideas:
-Download the latest drivers for your card from Intel -->Intel Linux Graphics
-Try this link for more help (but read it all before you start doing their solutions since some of the people get bad results and fix them later in the thread. --> [SOLVED] Setting higher resolution for Intel graphics controller in Ubuntu 11.04 [Archive] - Ubuntu Forums
Saw this too, so maybe try this after updating drivers if you haven't already.
- Resetting out of range resolution If you set a resolution inappropriate for your monitor in the Screen Resolution GUI tool, you can reset it by running rm ~/.config/monitors.xml from a terminal.
-Testing different resolutions You can either use the Screen Resolution GUI tool to experiment with different resolutions, or the more powerful xrandr command-line tool:
Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 1400 x 1400 VGA disconnected (normal left inverted right x axis y axis) LVDS connected 1400x1050+0+0 (normal left inverted right x axis y axis) 286mm x 214mm 1400x1050 60.0*+ 50.0 [...]
$ xrandr --output LVDS --mode 1024x768Code:
$ xrandr --output VGA1 --mode 1024x768
$ xrandr --output LVDS --mode 1024x768 --rate 75Code:
$ xrandr --output VGA1 --mode 1024x768 --rate 60
See if any of this helps. I'm just going from what I'm reading on other sites. I have a NVIDIA card and my settings are a lot easier to deal with IMO, since I just go to NVIDA settings, and then fiddle until I get both my screens working (took a few days to get my duals up and running, but everything is GREAT now.)

Obviously replace your desired settings in the xrandr command tho forgot to tell you, but I'm sure you would realize that

Let me clear some things up.
- I am using Gentoo now.
- I want to connect my laptop to my tv. so, dual monitor.
- Ubuntu detects and applies my monitor resolution (1360x76.
- xrandr in Gentoo does not list 1360x768.
- I calculated modline by cvt and added it to xrandr. When I applied that to my TV, it said something like the resolution is not supported.
I have already tried the xrandr method, but I think I messed up somewhere and got modlines wrong.
I am going to try people posted in that Ubuntuforum thread.
Thank you for your help.

OK, so you tried the cvt way? Did you follow all the directions? I'd assume you did, but there is a lot more to it then just cvt.
Heres a detailed one ---> How change display resolution settings using xrandr
Just throwing that out there... That should make Gentoo's xrandr list your setting that you add to it (e.g. 1360x768 ). Sorry if you tried all that!!
Anyway, have you tried "grandr" in the Ubuntu Software Center? Just type in grandr, but it's called "Multiple Screens" as a title (does gentoo have a software center? I know nothing about this so called "gentoo" ). It adds a little extra to your "xrandr". May help, IDK though.
Or "ArandR"? These are just different programs to maybe help with the problem, instead of going in and configure your xorg.conf. If I had the choice, I'd definately rather not .
Try all this sh*t man, and if it don't work hit me back up and I'll see what I can do to try and help some more, or maybe someone else will post a quick fix, and help us both out. It's just hard to fix things like this when I'm not the one fiddling with it using trial-and-error myself, then moving onto something else...
but check this out too,
X.Org/Dual Monitors/Intel <---may be your ANSWER since it's specifically based around you Intel driver. Maybe try this before you go in and start messing around with the .conf .
It seems the intel driver cannot handle a Virtual section larger than 2048 per 2048. This means that if you want to set a 1440x900 screen aside a 1280x800 screen, it will fail.
P.S. Hope something here works for you!!!

There is a work around though I think I read. Just try that link above and let me know how it goes!!

I copied the modeline from /var/log/Xorg.conf in Ubuntu. I will try it in Gentoo soon. I am almost certain that it will work.
By the way, Gentoo has package manager but it does not have something like software center. I don't know of any GUI package manager. Command line is easy and neat enough.
Thank you very much. You have been very helpful. I will mark this thread as solved if I don't need further help.
