I installed Lubuntu on a HP2140 mini PC. Everything is working perfectly, except for the screen resolution. According to the specs it can do 1366x768.

I tried setting this resolution with xrandr, with both ctv and gtf to get the Modeline. But when I try to add the mode, it gives me:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  30
  Current serial number in output stream:  31

It's such a shame, because if I upgrade it with SSD and a little more RAM it could be a nice little mini book.

lspci gives me:

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GSE Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

What exact model do you have? There where both 1024x576 and 1366x768 models of the HP mini 2140. Might be a stupid question, but I often don't remember which screen I've got on my thinkpad... :)

  • I remembered that the original Windows XP ULCPC had that 1366x768 resolution, but now you made me doubt myself. I'm not sure where I can find this info on the laptop itself though. Maybe I should try and install windows xp again. – rolandow Jan 13 '16 at 10:24
  • Check the product number or serial number (normally) on the back of the computer. Go to hp support site and search for this number and you'll be able to find the specs for it. – jogco Jan 13 '16 at 10:28
  • The models are described in this document – jogco Jan 13 '16 at 10:36
  • But there is no 1366x768 model listed.. – jogco Jan 13 '16 at 10:52
  • I tried searching by serial number. I could fetch information about warranty, but not about the specific hardware. I know Dell stores all information like this by service tag, but apparently HP doesn't. The document you provided says 10.1-inch diagonal 16:9 HP Illumi-Lite LED scratch-resistant display (1024 x 576 or 1366 x 768) on page 3. – rolandow Jan 14 '16 at 11:17

I have an HP 2140 too, with 2GB of ram, and I had an SSD inside. And the bottleneck of this system is the Atom processor. Which was indicated by a Win 7 system test. I had a dual boot with Lubuntu. It's only the start-up time that gets shortened, it doesn't make the system faster or extend battery life. I took the SSD out and going to reinstall Lubuntu again. Just to let you or other people know, who get tempted to install an SSD in this system.
