手里有一个4k本子，不知道ubuntu能否支持啊？担心字体超级小，或者有毛刺。。。提前问一下，谢谢

只要安裝合適的顯卡驅動
Ubuntu 支援 4K

unity和gnome的话可以直接在设置-->显示里面调节整体缩放

感谢回复，中午已经装上了，不得不说，ubuntu对4k屏的支持，比win8.1强不少 :em11

楼主是怎么设置的呢？我想把分辨率调小到高清，但我的dell-m4800笔记本4k屏幕装的ubuntukylin系统，分辨率总是调整不成功，驱动从开源X.org换成Nvidia的专用tested驱动也还是不成，设置完后注销再登陆会出现分辨率是小了，但是鼠标点击却还在4k分辨率里。。。。

听说fvwm能解决。。但还不知道怎么设置

依旧是不成功～
在驱动是开源xorg的时候，无论是系统设置里设置1920x1080，还是用xrandr其他分辨率，都会直接黑屏..... 我通常都是ctrl+alt+f1盲打要求sudo shutdown后电脑会自动亮屏到登陆界面。
在驱动改成NVIDIa的时候，系统设置里就只有3200x1800分辨率，但xrandr -s 5 可以暂时的得到我想要1920x1080分辨率，于是我按照您给我发的链接打算加入新模式1920x1080分辨率，却各种失败，下面就是我的终端内容：
（笔记本基本环境：dell-m4800笔记本，win7+ubuntukylin15.10双系统独立安装在两块ssd硬盘上，ubuntukylin15.10新装后仅在ustc源update&upgrade过，再其他的就什么都没有安装过或设置过了）

0. 你在 monitor 及顯卡之間使用什麼連接線 ? 有沒有 dvi 連接線及插口 ?

引用:

dell-m4800 笔记本

1. 把下面指令複製貼進終端機執行
1-1. uname -r
1-2. sudo lspci -knn
1-3. sudo lshw -numeric -class video
1-4. sudo ubuntu-drivers devices
把結果直接選取/複製貼上來

不知道下面的图是不是你想了解的：似乎没有所谓的DVI？

另外，我现在外接了一个VGA显示器，显示器显示分辨率是正常的，但是笔记本的显示仍然是有问题的，分辨率降不下来。
