Ongelma on lähes ratkaistu, eli hertsit pysyy buutin jälkeen 

Mutta...näyttäisi siltä, että koneeni käyttää kaksia eri ajureita (nv ja nvidian rajoitettuja 100.14.19) ja tähän haluaisin kyllä pikaisesti neuvoa, miten toimia?
Alla on hieman kerrottu siitä mitä olen tähän saakka tehnyt1. Varmuuskopio omaan kotikansioon
sudo cp /etc/X11/xorg.conf /home/käyttäjätunnuksesi/xorg.conf_backup2. Tämä komento muokkasi xorg.conf-tiedostoa haluamaani suuntaan
sudo nvidia-xconfig --add-argb-glx-visuals3. Otin xorgista kopion työpöydälle, jota aloin muokkaamaan
sudo cp /etc/X11/xorg.conf /home/käyttäjätunnuksesi/Desktop/xorg.conf
4. Poistin tiedoston: /home/käyttäjätunnuksesi/.kde/share/config/displayconfigrc (kotikansio->näytä->näytä piilotiedotot) ja sitten koneen buuttaus
sudo shutdown -r now5. Seuraavaksi valitsen nvidian asetukset (resoluutio 1280x1024 ja 100Hz) painan apply ja quit
sudo nvidia-settings6. Kokeilen säilyvätkö asetukset-> Ctrl+Alt+backspace->kirjaudun uudelleen sisään ja tarkistan-> nvidian asetukset  

7. Jos jotain sattui menemän mönkään, niin otin käyttöön alkuperäiset xorg.conffat ja yritin uudelleen  

sudo cp /home/käyttäjätunnuksesi/xorg.conf /etc/X11/xorg.confstartxJa tältä se näyttää nyt# nvidia-settings: X configuration file generated by nvidia-settings
