Zvětšené pracovní prostředí po upgradu na verzi 18.04 s nemožností změny

[manime]

Ahoj,
upgradovala jsem starší LTS verzi na nejnovější dostupnou, ale bohužel už při přihlašovací obrazovce a následně i po přihlášení se pracovní prostředí neúměrně zvětšilo a nemohu s tím cokoli dělat ani v Nastavení systému, ani nikde jinde. Začínám být zoufalá, předtím bylo vše ve vyhovujícím standardním rozlišení...bohužel se takto nedá pc normálně používat .

Skus spustit software&update(softver a aktualizacie), tam sa hore prepni na kartu ubuntu softvare a zafajkni vsetko okrem source code. To iste sprav aj na karte other softvare(softver tretich stran).
Zatvor to okno tlacidlom zatvorit(ukoncit, close), nie krizikom. Budu sa ti obnovovat zoznamy balickov, ak sa ti to podari zatvorit tak ze sa neobnovia spusti prikaz

Kód: [Vybrat]

sudo apt-get updatePotom znovu otvor ten softver a aktualizasie a prepni sa na kartu aditional drivers(dodatocne ovladace), chvilu pockaj aby sa nacitali a ak tam budes mat dajaky pre graficku kartu daj ho nainstalovat.

Po spuštění tlačítka Ukončit mi systém oznámí, že SW je aktuální a žádné aktualizace se neaktivují; po spuštění příkazu v Terminálu je výstup následující:

Mas tam stary repozitar pre predchadzajucu verziu. Spusti

Kód: [Vybrat]

sudo nano /etc/apt/sources.listNajdi tam riadky ktore maju v sebe precise a daj pred ne(na ich zaciatok) znak #
Ulozis to cez ctrl+o a zatvoris ctrl+x
potom skus znova to update.

[manime]

Update proběhl úspěšně, bohužel seznam dodatečných ovladačů je prázdný. Mám proto stáhnout ovladač přímo z webu výrobce a nainstalovat?

[manime]

Tak pomocí http://www.linuxandubuntu.com/home/how-to-install-latest-nvidia-drivers-in-linux mám nyní dostupné ovladače ke grafice (viz obrázek). V nabídce Nastavení systému -> Displeje je stále nabízeno jediné rozlišení obrazovky.

[TIBOR]

Tiez aj ked zvolis ten nvidia ovladac? Daj sem este ako prilohu subor
/var/log/Xorg.0.log

[manime]

Když zvolím nvidia ovladač a dám Uplatnit změny, samo to přeskočí na tu druhou variantu.

1. A jak to vypadá (či vypadalo) v live? 

2. Upgrade je často problémový - udělej čistou instalaci nejlépe se zachováním /home

[manime]

Teď to vypadá následovně...

Ono nejlepší by bylo to stejně vidět v reálu. Jedno písmeno má u mne na obrazovce cca 1 cm na výšku..

Ad 2/ U mne vždycky probíhaly upgrady dobře, řešila jsem jen drobnosti. Pokud nikdo nic neporadí, jak to vyřešit bez čisté instalace, tak to zítra zkusím s ní.

[juwa2]

Jak to vypadá vím.
Odpověz na první otázku. 

Ad 2/  Jediný upgrade který se (u mě) povedl byl 12.04 >> 12.10  Všechny další skončily nevalně (vždy jsem si nejprve vytvořil zálohu systému - systémového oddílu /  pomocí Clonezilla). Od té doby vždy dělám pouze čistou instalaci. Abych si to maximálně usnadnil, tak:
1.) /home mám na zvláštním oddíle, vždy ho zachovám (= při instalaci neformátuji).
2.) Veškerý nainstalovaný SW si nejprve zálohuji pomocí Aptik. Zálohu si uložím do /home (záloha má pouze cca 2MB).
3.) Pak tuto zálohu do nové instalace (opět pomocí Aptik) obnovím. Výrazně to urychlí celý proces. A hlavně na žádný program nezapomenu...

Mozno by som skusil este pozriet do /etc/X11 ci je tam subor xorg.conf ak ano skus ho zmazat a restartovat.
Inak ak nemas problem s reinstalom, bude to asi najrychlejsi sposob.
Pre buducnost treba pred povysenim system zalohovat napr. cez timeshift a este pred povysenim treba odinstaloat neslobodne ovladace ktore najcastejsie robia po povyseni problem.

[manime]

Ad juwa2: tak to jsme si na první neporozuměli... boot z usb budu popisovat níže..

Ad TIBOR: vymazání xorg.conf a restart nic nevyřešilo.
Zkoušela jsem nyní boot z usb a ten vypadá v pořádku.

[Rellik]

Nemáš tam dualboot s windows? Mě to něco podobného dělalo právě kvůli tomu. Všechno zvětšené a nastavení rozlišení nešlo měnit...  Pomohlo to vyřešit až odebrání "security klíčů"  v UEFI biosu...

[manime]

Dřív jsem dualboot měla, ten byl u mne naopak bez problémů. Nyní mám jen ubuntu. Mrknu do BIOSu...

Edit: v BIOSu nic nenalezeno (anebo nevím )
