Driver nVidia: finalmente una tregua.

 

Non so quanti dei lettori e, soprattutto, dei possessori di una scheda video nVidia abbiano incontrato i miei stessi problemi ultimamente. Prima l’impossibilità di usare Compiz-fusion con il kernel 2.6.30, poi problemi del DKMS con kernel 2.6.31, e ancora problemi (che non ho approfondito) nel caricamento del modulo nvidia…come potete vedere da queste righe del file Xorg.0.log:

dlopen: /usr/lib/xorg/modules/drivers/nvidia_drv.so: undefined symbol: resVgaShared
(EE) Failed to load /usr/lib/xorg/modules/drivers/nvidia_drv.so
(II) UnloadModule: “nvidia”
(EE) Failed to load module “nvidia” (loader failed, 7)

Insomma alcuni possessori di schede nVidia avranno desiderato una tregua.

E la tregua (almeno per me) è arrivata! Grazie alla versione 190.42 dei driver proprietari, reperibile sul sito ufficiale:
http://www.nvidia.com/object/linux_display_ia32_190.42.html

Installiamo, al solito, seguendo questi passaggi:

  1. Spostarsi nella console tty1, tramite la combinazione di tasti Ctrl-Alt-F1.
  2. Chiusura del server grafico. Se avete Ubuntu:

    sudo /etc/init.d/gdm stop

    Se non avete Ubuntu o non usate GDM, adeguate il comando.

  3. Installazione dei driver nVidia:

    sudo sh /path/to/NVIDIA-Linux-x86-190.42-pkg1.run

    dove a /path/to va sostituito il percorso in cui risiedono i driver scaricati.

Bene! Abbiamo installato i driver e siamo pronti ad utilizzarli. Non ho notato problemi di sorta e anche Compiz-fusion va alla grande. Ecco i risultati di glxgears con la mia Geforce Go 7300:

4103 frames in 5.0 seconds = 820.547 FPS
4116 frames in 5.0 seconds = 823.184 FPS
4101 frames in 5.0 seconds = 820.159 FPS
4114 frames in 5.0 seconds = 822.793 FPS
4107 frames in 5.0 seconds = 821.372 FPS
4100 frames in 5.0 seconds = 819.977 FPS

    It is important for the seller to be sure and confident that he is taking the right step.
    We would venture to say that the overall cost of production varies greatly in Canada depending on which province is utilized, via labour
    and other geographical incentives. There probably isn’t a day when Canadian business owners and financial managers don’t hear about
    factoring and accounts receivable financing as a method of financing their business in Canada.

    Accounting is an art of correctly recording the day to day business transactions: It is a science of keeping the business records
    in a regular and most systematic manner so as to know the business
    results with minimum trouble. Performing the same tasks that can easily be handled by an online business at cheap rates doesn’t seem to make
    business sense either. Hence, other civilizations,
    particularly the Greeks and Romans, likewise made use
    of this light material for their writing and documentation purposes and replaced the cumbersome clay tablets and geometric tokens popularized
    by Mesopotamia. Double-entry bookkeeping requires recording
    of each transaction twice using debits and credits which serves as a type of error protection system.
