Zdravim
Mam problem s nvidia driverem na GPU: GeForce G102M, Gnome mi pada do fallbacku, ptze nejede akcelerace. Nvidia driver jsem na tomto stroji pouzival nekdy do leta 2012, kdy po jednom z updatu jadra a nvidia ovladacu mi to zacalo zlobit. V tu dobu jsem nemel prilis mnoho casu se tim zabyvat a jelikoz jsem nvidia driver pouzival jen kvuli HDMI, ktere jsem v te dobe jiz nepotreboval, vratil jsem zpet nouveau. Pred casem pro linux vysla jedna z mych srdcovek a sice CS1.6, u ktereho na nouveau mam jen asi 15-20 fps, zatimco na windows 100fps. Chci tedy vyzkouset, jak to pojede na nvidia driveru, ale po vic nez pul roce znovu narazim na stejny problem jako v lete. Bohuzel jiz nevim, se kterou verzi se mi to rozbilo

Podle release notes na nvidia strankach je tato karta stale mezi podporovanymi.
Postupoval jsem nasledovne (zkousel jsem i akmod misto kmod-nvidia):
[root@asus ~]# yum install kmod-nvidia
Instalace probehla v poradku, vcetne zavislosti jako napr.: xorg-x11-drv-nvidia, xorg-x11-drv-nvidia-libs, …

Normalne, zadny xorg.conf nemam, ale zkousel jsem i nechat si jej vygenerovat pres nvidia-xconfig a nvidia-settings, ale ani jedno nepomohlo.
Myslim, ze v xorg.conf problem neni. Na nouveau s tim nemam problem.
Google vetsinou radi reinstall nvidia driveru, ale to jsem udelal uz asi 5x a porad to same.
Nez vyzkousim drivery stazene primo na nvidia.com, nenapada nekoho co bych s tim mohl jeste zkusit?
