Ubuntu出現 The system is running in low-graphics mode解決辦法

                                    

在網上查了一下,解決的方法很多,終於找到了一個適合我這裡問題的方案,引用如下: 

I have recently received a similar issue with myPangolin Performance laptop. The folks at System 76 told me to do the following:

Click Okay and then select the option to get a terminal. (alternatively you can press ctr alt f1 to bring up another tty)

sudo chown lightdm:lightdm -R /var/lib/lightdm
sudo chown avahi-autoipd:avahi-autoipd -R /var/lib/avahi-autoipd
sudo chown colord:colord -R /var/lib/colord
sudo reboot

附:在網上還找到另外一種方式,安裝網絡卡驅動:

# 對於最新的Nvidia二進位制驅動:

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current nvidia-current-modaliases nvidia-settings

# 對於最新的ATI/AMD二進位制驅動:

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install fglrx 

我安裝的是nvidia的驅動,重啟後進入到登入介面,輸入使用者名稱密碼後還是無法進入桌面,一直在登入介面迴圈,解決辦法如下:

 alternatively you can press ctr alt f1 to bring up another tty

解除安裝nvidia驅動:

sudo apt-get remove --purge nvidia-*
sudo apt-get install ubuntu-desktop
sudo rm /etc/X11/xorg.conf
echo 'nouveau' | sudo tee -a /etc/modules
#重啟系統
sudo reboot

重啟之後即可。

原因查詢:

# cd home 檢視是否有.xsession-errors
cd ~
ls -a
#用vi開啟.xsession-errors檔案
vi .xsession-errors

接著你就可以看到裡面的日誌資訊,按照日誌裡面的資訊去baidu,也許可以解決驅動安裝的辦法。
