ウェブを大量に検索した後でも、2番目のモニタを希望のより高い解像度（1920×1080）に設定することはできません。
ハードウェア：Intel ATOM x36/37オンボードGPUは、ASUS HDMIモニターとDell VGAモニター（両方とも23インチHDモニター）を駆動します。
X -configurelightdmを停止して失敗した後：生成された画面数が検出されたデバイスと同じではなく、生成された画面がx.conf.newWebの例と異なります（参照）https://community.linuxmint.com/tutorial/view/877)
xrandr --addmode VGA-1 1920x1080セッション中は動作しますが、永続的ではありません。
Xorg.logは動作しますが、長すぎます...
どんな助けでも大変感謝します。
