Ubuntu 14.04 不保存螢幕解析度

我正在使用 Gnome 執行 Ubuntu 14.04。每次重新啟動電腦時，我都必須手動將螢幕解析度設置為較低的解析度。

為什麼不自動保存？

一些輸出：

$ lspci

00:02.0 VGA compatible controller: Intel Corporation Core Processor
Integrated Graphics Controller (rev 12)

$ uname -a

Linux mediaserver 4.2.0-42-generic #49~14.04.1-Ubuntu SMP Wed Jun 29
20:22:11 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

$ ls /usr/bin/*session

/usr/bin/gnome-session

$ echo $DESKTOP_SESSION

gnome-fallback

/var/log/Xorg.0.log

在創建具有以下內容的*/etc/X11/xorg.conf*文件後修復：

Section "Monitor" Identifier "Monitor0" Modeline "1280x720_60.00"
   74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
EndSection
Section "Screen" 
   Identifier "Screen0"  
   Device "Card0"  
   Monitor "Monitor0"
   SubSection "Display"  
       Modes "1280x1024_60.00" "1024x768_60.00" 
   EndSubSection
EndSection 
Section "Device" 
   Identifier "Card0" 
   Driver "i915" 
EndSection
