Ubuntu - problemi z ekranom

Takole je: leto nazaj sem imel ekran velikosti 1024x768. Ker je to seveda precej malo, sem vzel nekaj večjega 1280x1024. Problem je, da mi Ubuntu pri prižigu računalnika vsake zmanjša resolucijo na 1024x768 in izvrže tole errorsko sporočilce:

Could not apply the stored configuration for monitors

none of the selected modes were compatible with the possible modes:

Enako se zgodi, če se ekran čez nekaj časa (neaktivnost in to) sam zaklene. Tudi takrat se resolucija zmanjša, samo sporočila ne javi. Nenavadno: resolucija se ne zmanjša, če računalnik zaklenem ročno.
Ta problem začasno rešim tako, da odprem program Displays, ki očitno avtomatsko zazna, da nisem na največji možni ločljivosti in jo zamenja. Vendar to traja samo, dokler se računalnik zaklene ali znova prižge.

Ali je že kdo imel težave s tem? Jih zna kdo rešiti?

P.S.: Uporabljam Ubuntu 12.10 prek Wina. Naložen imam še Cinnamon, vendar so se problemi pojavljali že preden sem ga naložil. Na Windows 8 je z ekranom čisto vse v redu,

Okej, sem zbrisal. Upam, da bo delalo.
