整个系统突然不认得所有png格式的图片了...555....

Osirix

启动X时出错,提示
"装入主题happygnome出错,无法识别文件
/usr/share/gdm/themes/happygnome/options.png
的图象文件格式"

刚刚更新了一下系统,重启后就出这个问题了...
可以在shell下更改 在登陆X时,是否要载入主题吗?

应该改哪个配置文件呢?
/etc/X11/gdm/gdm.conf?

3. # edit this, or you can optionally just edit this file by hand.  Note that
   
4. # gdmsetup does not tweak every option here, just the ones most users
   
5. # would care about.  Rest is for special setups and distro specific
   
6. # tweaks.  If you edit this file, you should send the HUP or USR1 signal to
   
7. # the daemon so that it restarts: (Assuming you have not changed PidFile)
   
8. #   kill -USR1 `cat /var/run/gdm.pid`

改gnome主题怎么会跟gdm有关系呢?
他们不扯什么关系.
你到底要改那个啊?

狱卒

将运行级别改成3，启动之后直接startx进入X，这样做的目的是跳过GDM的步骤，进入X后将GDM登陆界面改掉，再次运行GDM，看看故障是否依旧存在。

Osirix

而且换了其他主题都不行, 一启动X, 均提示"无法识别....png图象文件格式"

但系统是已经装了libpng的,

这有可能哪儿出问题了呢?

Osirix

可是现在一startx, 就出来个框框提示"无法识别....png图象文件格式"

然后就什么都动不了了, 只能Ctrl+Alt+F切换个Console出来用....

Osirix

Linux对图象格式的识别应该不是基于扩展名, 那是通过什么识别的呢?

只需要调用libpng就可以了吗?

Osirix

sorry, 重新试了下
按狱卒朋友的建议, 用init 3登陆后 startx, 是可以登陆进桌面, 但是登陆后马上有一大堆"无法识别图象文件格式"的提示, 桌面任务栏上的快捷方式图标 也全变成了叉叉

打开文件浏览器, 原来漂亮的文件夹和文件图标也全变成了一白框, 很不好看

所有的png文件用系统默认的"图片查看器" 打开, 也是一片空白

但是桌面背景图片可以正常显示(那个桌面图片是JPEG格式)


感觉好象是整个系统突然不认得png格式的图片了.....

Osirix

can anyone help me?

Osirix

哎, 已经两天没进X了.....
