我有一个惠普 Compaq nc8430显示器应以 1680x1050(16:10)分辨率运行,但从 17.04 升级到 17.10(Artful Aardvark)后,分辨率只能设置为 1400x1050(4:3),并且会出现椭圆形。
解决该问题的一种方法可能是降级到 17.04,但从长远来看这并不能解决问题。
我已经xserver-xorg-video-radeon
安装了。
# grep EE /var/log/Xorg.0.log
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
[ 47.455] (EE) open /dev/dri/card0: No such file or directory
[ 47.469] (EE) Screen 0 deleted because of no matching config section.
[ 47.550] (EE) AIGLX: reverting to software rendering
我是否错过了一些firmware
?
$ aptitude search firmware | egrep -i "ati|radeon"
(no result)
图形适配器是:
# lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV530/M56-P [Mobility Radeon X1600]
我试过了radeontop
但是我猜卡太旧了:
# radeontop
Failed to open DRM node, no VRAM support.
Unknown Radeon card. <= R500 won't work, new cards might.
xrandr
说同样的话:
$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1400 x 1050, current 1400 x 1050, maximum 1400 x 1050
default connected primary 1400x1050+0+0 0mm x 0mm
1400x1050 77.00*
任何帮助将非常感激。
