LMDE 201403 Cinnamon, Update Manager says system is up to date.
I am running on an Acer netbook, Aspire ONE D257, screen resolution is 1024 x 600. The screen is quite usable but with only 10" approx diagonal measurement it means my not-so-young eyes need reading glasses to read it. So I plugged in a 20" external LCD display with nominal resolution 1600 x 900 which is much the same aspect ratio as the internal screen, and I can read it without the use of reading glasses (at least when it's attached to a desktop). What happens is the external display shows about one quarter of what is on the internal screen, in quadruplicate. Not very usable. If I power up with the external display connected and powered on, I get a duplicate (mirror) of what shows on the internal screen, however at a resolution of 800 x 600. Not very effective as for many websites, 1024 x 600 is pretty marginal anyway and 800 x 600 is worse. If I set the internal screen OFF in Display, and select a higher resolution for the external screen, then Cinnamon crashes and needs to be restarted. And after it restarts, what shows on the external screen seems to be a subset of what should be there, as the panel (bottom line of desktop) is not visible. And I end up powering off.
What I would like ideally is to automatically use a higher resolution on the external display (when connected and powered on) and to automatically to use the native 1024 x 600 on the internal screen when it is the only display in use.
I've looked at the forums and it seems people have been trying to do that with various netbooks for at least the last 5 years but it is not clear to me that anyone has been successful. There are references to using a randr utility, which is not in the Synaptic Package Manager list, so that is not very helpful to a newbie. LXRANDR is there and I've installed it but the results are the same as using Display - see above.
btw, I have to say that Windows 7 Starter, on this netbook, does what I want, no fuss. But I don't want to use Windows.
