詭異的問題+雜問 - Linux

最近拿到一台古老的P4 1.8G電腦（出廠預裝的是win98se）
顯卡用的是nvidia TNT2
os 裝的是debian lxde testing
nv驅動由nvidia網站下載Latest Legacy GPU (71.86.xx series): 71.86.15

現在碰到幾個問題：
1.編譯完nvidia non-free驅動後可以進桌面。但重開機後又不行了。
變成我每次開機都要重編譯一次......(這超奇怪)
2.螢幕是1024x768的，但dpi值卻是設定在68。文字超級小。
想要從xorg.conf設定，執行xorg -configure後卻出現有error。
（log放在最後面）
而且產生的xorg.conf也有問題。
-------------------
然後是這次安裝的機器及之前裝的eeepc(一樣是只裝lxde)的一些問題。
1.插隨身碟無法掛載。會顯示：Not Authorized (舊pc及epc均是如此)
可是我已加入plugdev群組了呀。
目前我是用pmount手動掛載，ok。
我的桌機無此問題，但有裝gnome,kde.....所以我在想是否漏裝了什麼？

2.無法待機、筆電無法合蓋待機。
之前有人說是老bug，可是我更新後仍舊如此。
目前我的eeepc也無法經由lxde關機選項中的待機進入待機/休眠模式。

3.這次裝的機器沒有powerdev群組，所以我的帳戶中沒有關機選項。
是否直接新增一個powerdev群組再加入帳戶就行了呢？

很多問題，希望知道的人能提供解答囉！
