Screen resolution on Samsung N150 netbook

[John F. Eldredge]

At last night's meeting, I mentioned that my Samsung N150 was capable of 1024 x 768 resolution in Windows 7 Starter Edition, but would only give me 1024 x 600 resolution in Ubuntu, and I was trying to figure out how to get the higher resolution in Ubuntu. Unfortunately, I learned today that the supposed 1024 x 768 mode in Windows is achieved by having the driver discard 168 scan lines of info, presumably spaced out across the screen, so the real resolution is only 1024 x 600. I have run into a couple of programs on Ubuntu, notably the Pan Usenet program, that open dialog boxes that are a full 768 pixels high, and have command buttons off-screen when used on a 1024 x 600 display.

Bummer, John. I am reminded of my dad's favorite retort: don't believe
anything you read and only half of what you see... ;)

Thanks for pointing out how to enable Ctrl-Alt-Backspace last night.
Big help.

I don't know anything about your Windows driver, but it's possible that it's doing scaling or resampling, as opposed to decimation (discarding lines.)  Either way, you don't have a true 768 pixels vertically, but the display may be quite usable if it's appropriately scaled.

On the down side, any scaling that's done by the CPU is taking away from other resources.

I would guess that it is doing some form of scaling or resampling, as I found a statement online that the machine was slower in 1024 x 768 mode than in 1024 x 600 mode.

John,

I saw a bug report about changing brightness on the Ingel GMA3150
graphics chipset. You might consider putting in an official bug
report for the resolution. It appears that the 1024x600 is native
resolution, so you might be out of luck getting someone to drive it to
the 1024x768 like Windows does.
