This article is about how to solve the problem of mouse blurred screen in CentOS system. I think it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it.

Because once after installing the CentOS system, there suddenly appeared the phenomenon of blurred screen, and even the mouse could not be managed.

(1) after the CentOS system is installed in vpc, a blurred screen appears when it starts to enter the Gnome desktop environment. Reason: because VPC does not support 24 colors of Linux, only 16 colors are used, while Linux defaults to 24 colors. Therefore, you need to manually change the "/ etc/X11/xorg.conf" file. After the modification of EndSection is completed, and after restarting, enter startx on the command line to enter the graphical interface.

The Java code Section "Screen" Identifier "Screen0" Device "Videocard0" DefaultDepth 24 SubSection "Display" Viewport 00 Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" DefaultDepth 24 SubSection "Display" Viewport 00 Depth 24 EndSubSection EndSection was modified to Java code Section "Screen" Identifier "Screen0" Device "Videocard0" DefaultDepth 16 SubSection "Display" Viewport 0 0 Depth 16 Depth EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" DefaultDepth 16 SubSection "Display" Viewport 0 0 Depth 16 EndSubSection

(2) Cent OS 5.3 installed in Vistual PC 2007 cannot use a mouse. This is not a problem with vpc itself, but a bug of the linux kernel. This needs to be done by modifying "/ boot/grub/grub.conf". It is important to note that the linux kernel version of Cent OS 5.3 is 2.6.18-128.el5. The default installation of grub.conf in Cent OS is:

Java code title CentOS (2.6.18-128.el5) root (hd0,0) kernel / vmlinuz-2.6.18-128.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet initrd / initrd-2.6.18-128.el5.img title CentOS (2.6.18-128.el5) root (hd0,0) kernel / vmlinuz-2.6.18-128.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet initrd / initrd-2.6.18-128 The revised content of .el5.img is: Java code title CentOS (2.6.18-128.el5) root (hd0,0) kernel / vmlinuz-2.6.18-128.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet i8042.noloop initrd / initrd-2.6.18-128.el5.img title CentOS (2.6.18-128.el5) root (hd0,0) kernel / vmlinuz-2.6.18-128.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet i8042.noloop

Initrd / initrd-2.6.18-128.el5.img is saved and rebooted. After entering the system, the mouse moves to the vpc screen and press the alt key to the right of the space to switch between the virtual machine and xp. These two problems appear in both fedora and CentOS systems, but similar problems have not been found in ubuntu and can be solved by using the above two methods. By the way, vpc works well in vista (this was tested in vista when I modified these two issues, and it works as well as xp).

The above is how the CentOS system solves the problem of blurred mouse screen. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
