Debian10へNVIDIAドライバをインストール

Posted at

###1. non-free contrib の追加

/etc/apt/sources.list

deb http://ftp.jp.debian.org/debian/ buster main non-free contrib 

###2. nvidia-detect をインストール/実行してドライバのdeb名を得る。

Detected NVIDIA GPUs:
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF108GLM [Quadro 1000M] [10de:0dfa] (rev a1)

Checking card:  NVIDIA Corporation GF108GLM [Quadro 1000M] (rev a1)
Your card is only supported up to the 390 legacy drivers series.
It is recommended to install the
    nvidia-legacy-390xx-driver
package.

###3. ドライバのインストール

apt install nvidia-legacy-390xx-driver

再起動する

トラブル

####Resolutionが勝手に設定され、文字が大きくなりすぎる
手持ちのHPのノート(解像度1920x1080)では、NVIDIAのドライバにより
DPIが自動的に139x144に設定されてしまう。

NVIDIAのコントロールパネルから"X Server Display Configuration"を選択し、
"Save X Configuration"ボタンで、
/usr/share/X11/xorg.conf.d/90-nvidia.conf として保存し、以下の行を追加する。

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    ....

    Option "UseEditDpi" "FALSE"
    Option  "DPI"   "96x96"
EndSection

UseEditDpiとDPIを追加すれば手動で設定できる。
