ROOTLESS_X has been disabled in n450 for now. Atom-pc still sees this failure. 17706 1 richard.purdie 2011-12-16 08:21:20 +0000 Does http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=ccc84d94b8ff59365806b57fe90a7bacdeb16b5d fix this? 17708 2 dvhart 2011-12-16 09:57:21 +0000 No, but the error changes: Fatal server error: xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted) 17804 3 edwin.zhai 2011-12-21 17:41:45 +0000 (In reply to comment #2) > No, but the error changes: > > Fatal server error: > xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted) This is he same error mesg if I enabled rootless X in qemu. The issue is that rootless requires KMS in kernel config, which depends on physical DRI. Qemu doesn't support DRI, so it failed. What about n450? 18062 4 edwin.zhai 2012-01-10 17:48:10 +0000 (In reply to comment #2) > No, but the error changes: > > Fatal server error: > xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted) I have checked latest master (021848b), things are a little bit different: rootless X start fail because xuser has no home directory. After create a new user with right permission as xuser, I can start rootless X as the new user. Also checked the kernel config of atom-pc, KMS is enabled by default. So the issue here is that useradd.bbclass fail to add the home directory even with the fix http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=ccc84d94b8ff59365806b57fe90a7bacdeb16b5d I'll open a new bug for it, and make this bug depends on it. 18670 5 josh 2012-02-21 11:51:05 +0000 (In reply to comment #4) > (In reply to comment #2) > > No, but the error changes: > > > > Fatal server error: > > xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted) > > I have checked latest master (021848b), things are a little bit different: > rootless X start fail because xuser has no home directory. After create a new > user with right permission as xuser, I can start rootless X as the new user. Do we know why rootless X requires a home directory? Presumably this is just so that the X server has somewhere to write files? Can we use /tmp instead? 18678 6 edwin.zhai 2012-02-21 17:14:34 +0000 (In reply to comment #5) > (In reply to comment #4) > > > > I have checked latest master (021848b), things are a little bit different: > > rootless X start fail because xuser has no home directory.

Presumably this is just so > that the X server has somewhere to write files? Can we use /tmp instead? It's not the perfect solution. Even can start rootless X, we still have various failure without HOME directory. e.g open matchbox-terminal. Fix it on useradd is the right way, I think, 19671 7 edwin.zhai 2012-03-30 05:19:05 +0000 After bug 1889 got fixed, I have tested latest atom image @ http://autobuilder.pokylinux.org/nightly/20120328-1/machines/atom-pc/core-image-sato-atom-pc.hddimg rootless X start successfully.
