 Posted: Thu Jun 23, 2005 3:53 pm Post subject: Hardened X.org: Blank screen, IO error 104 [SOLVED] |
 |
|
Yes, I have searched the forums, and read quite a lot of the posts but I just haven't found a solution to this.
So I re-installed gentoo (stage1), with hardened flags in make.conf and used gentoo-sources-2.6.11-hardened-r14. At first I got lots of ELF errors when doing a "startx", but after having emerged x11 with "dlloader" this wasn't a problem. But would X.org load? Nope. All I get is a blank screen, with a text cursor flashing.
New flags used during this re-installation:
| Code: | | CFLAG -fstack-protector-all, USE hardened pic dlloader (for x11) |
nvidia-kenerl and nvidia-glx are installed, nvidia module is loaded, opengl-update nvidia has been run and the xorg.config is correct AFAIK.
The error I get is:
| Code: | XIO: fatal IO error 104 (Connection reset by peer) on X server ":0:0"
after 0 requests (0 known processed) with 0 events remaining. |
The only error in Xorg.0.log is this:
| Code: | | (WW) Open APM failed (/dev/apm_bios) (no such file or directory) |
Is that error really the problem? It seems unlikely.. Any ideas?
"And I would do anything for you..." (almost) if you could help me with this *sighs*

Had I been a Good Human Being I would have remembered to disable some of the flags on /usr/bin/Xorg using paxctl. I have done that now, and although X.org still won't load, the error message is now somewhat more clear, and there's no blank screen.
| Code: | Fatal server error:
Caught on signal 11. Server aborting.
XIO: fatal IO error 104 (Connection reset by peer) on X server ":0:0"
after 0 requests (0 known processed) with 0 events remaining. |
Time for some forum searching! |

| After having compiled X.org using the "static" flag, and then realized that the nvidia driver doesn't work at all with hardened gentoo (right now/then) I wiped the disk and reinstalled again, without hardened flags/kernel. I'll just wait until things are a bit more mature. |

Xorg and hardened work just fine for me 
Admittedly, I don't use the binary nvidia drivers, hence I don't know about
how well they play with hardened at the moment.
In any case, make sure to NOT disable privileged I/O, otherwise
Xorg won't be happy.
| Code: |
# CONFIG_GRKERNSEC_IO is not set
|
Your initial error looks like it was caused by exactly this. |
