CentOS7 using normal before, always with a graphical interface, and then one day suddenly found the black screen,
Starts to the graphical interface, which is able to see the login background (only the login background, no login dialog) and a mouse, black screen,
Can enter the tty2

See
Pci id for fd 12:102 b: 0532, drivier (null) # said this sentence is not driving?
Behind the GBM: failed etc. # don't tube the

102 b: 0532 corresponding driver is Matrox G200ew
Matrox website has no G200 series driver available for download,
Online Matrox G200ew are not for Linux,

Totally have no idea,

Update:
$startx
Xauth: the file/root/. Serverauth. 58842 does not exit
Xauth: the file/root/. Xauthority does not exit
Xauth: the file/root/. Xauthority does not exit

Update 2:
After using the supermicro servers, start showing supermicro mark, then a black screen, after switching to tty2 startx
Will turn to a graphical interface, is merely an interface:
A problem has occurred and the system can 't recover. Both Please log out and try again.
After enter xauth below in addition to the newspaper... The file.. Not exist, the X Server has
X.orgPcii if for fd12:102 b: 0532, driver (null) # this is the same as before, but before can display graphical interface, so consider not drive problem, if is a problem of driver, how disappear?
Failed to bind extensions
Failed to load the driver: kms_swrast
EGL_MESA_drm_image required # I don't know what it is, and the required is needed or have?
Gnome - session - is - accelerated: llvmpipe detected. # seems to be the only normal word
Xinit: the connection to the X server lost # is currently in the directions

I also am such, can only see centos7 background picture, card in that do not show the login screen, cause the reason is that the kernel upgrade to 3.10, in time, in order to hold the lantern, go,
Used redhat, met the graphics card not drive incompatible problems, that moment seems to be completely black screen, change the mode of x11d to vesa can solve,
Now can see the background including the logo, it's not a graphics driver problem,

CodePudding user response:

Reshipment once, in order to compile the lantern installation, the language, after an upgrade, the kernel and associated upgrade, tragedy again, don't know can use xmanager remote connected,

CodePudding user response:

Into the interface, the card in the login, can CTRL + Alt + f2, switch to the command interface, then startx, find oh, no! Someting has gone wrong.

reference rgqancy reply: 3/f

Me too, this situation CentOS7 a few days ago with a good, never shut machine, turn it off and then turned on the day before yesterday, switch to the command interface login first, after login cannot enter commands, hint I later

CodePudding user response:

Should be lost/usr/lib64/dri/kms_swrast_dri. So the problem

CodePudding user response:

Everybody:
I don't have to install the system, repair the problem,
I'll find a lot of data, the essence is the Gnome washed-up, various attempts have no,
Later, I found my HP4411S (VT168PA) wireless network card (there was a little hardware switch can restart the network card), can I put my card to start networking (command interface)
I use the CTRL + Alt + F2, under the bash of the root account, you can use yum upgrade, upgrade the whole system, and then restart,
After the restart, surprised to find that, the kernel version (2 xx) upgrade from 3.10 to 3.10 (xx) 3, unexpectedly can enter the Gnome,
Too happy, to tell you that province reshipment system,

My previous centos7, then upgrade part of the package in the yum, knew it couldn't get into the system,
Then reshipment once, did not dare to upgrade, but in order to compile under centos7 install the lantern (the lantern website only support Windows and Android, Ubuntu, ArchLinux), so the support to install some new go 1.6 and Npm, make the busy, and can't get into centos gnome,

CodePudding user response:

Nature due to upgrade yum install some underlying library, which leads to the Gnome need component versions do not match,
I am stuck in where you can see the background image of "seven", but it doesn't show the login window, I use the CTRL + Alt + f2 to switch to the console interface,
Perform startx interface, at this moment will shine the gnome desktop (a flash out, desktop ICONS only a recycle bin), what will print a console interface error: server, according to the error was taken of the ditch, solve various attempts,
Button playing at last, the wifi hardware switch indicator light, found the console interface, prompt to find new hardware, and then use the curl can find on the Internet,
Yum had upgrade to install the new kernel (small version number has changed), system repair was set up,

CodePudding user response:

I suggest you, can be wired network card, even perform yum upgrade,

CodePudding user response:

I also encountered this kind of situation in the CentOS6.3 version, in the login screen,

CodePudding user response:

I, too, in the background image and seek solutions

rgqancy positive solution amount done thanks to wait for some time that I have updated the 2908 files I had forgot to plug cable update half discovered quickly with the estimate is turned off before the next good boot you doesn't automatically install the user experience is not as good as Microsoft,,,,

CodePudding user response:

My reason for the emergence of this problem is to modify the/etc/ld. So, the conf then execute the/usr/sbin/ldconfig, then I recover ld. So. Conf, perform the/usr/sbin/ldconfig, restart again

Yum upgrade can perfect solution, it should be part of the software depends on, upgrade to the latest version
