[Packard Bell EasyNote MH35] Wrong screen resolution after intallation Xubuntu 14.04

[maxmito]

Hi,
after I installed Xubuntu 14.04 the screen resolution is only 640x480, while if I run it LIVE, I get also higher resolutions (1024X768, etc).
My graphic card is a SiS 771/671 PCIE (from lspci).

For your information I also installed alongside Xubuntu, also Linuxmint 16 and the screen resolution is fine

[penalvch (penalvch)]

maxmito, did this problem not occur in a release prior to Trusty?

[maxmito (maxmito)]

It was a fresh brand new installation of Xubuntu.

I installed then Linuxmint 16 and I was able to get at least 1024x768.

[penalvch (penalvch)]

maxmito, for regression testing purposes, could you please test Saucy via http://releases.ubuntu.com/saucy/ and advise to the results?

[maxmito (maxmito)]

I will try with a live version on saucy

[maxmito (maxmito)]

With live version of Saucy I get 1024x768, but also with the 14.04 running live I could get this resolution, the problem happened when I installed it.

[penalvch (penalvch)]

maxmito, just to clarify, was their a prior version of Ubuntu that when you actually installed it, didn't reproduce this problem?

[maxmito (maxmito)]

It was a fresh brand new installation of Xubuntu 14.04 no other version installed.

[penalvch (penalvch)]

maxmito, for regression testing purposes, could you please test 12.04.0 via http://old-releases.ubuntu.com/releases/12.04.0/ and advise to the results?

[maxmito (maxmito)]

Hi Christopher I invite you to read again the thread :)

with:
14.04
13.04
12.04

All of them, running as LIVE, they are fine more or less, I can set a 1024x768 resolution.

If I install them no, I get get maximum 640x480.

I installed Linux Mint 16 and I don't have this issue, I can get 1024x768.

Thanks!
