Specifically, the drivers and commands that I used were as follows: modprobe sg modprobe usb-storage mount -t usbfs none /proc/bus/usb At this point, according to the kernel log, the drive was recognized but there were errors in reading and so I could not finally mount the NTFS file system that the drive contained. Fdisk could not recognize the drive. Using a Gentoo Live DVD to boot Linux, the drive was recognized without any read errors. In this case fdisk could recognize the drive. I then attempted to reformat the drive with an ext2 file system but the format failed. After reading bad on-line reviews for this particular Seagate USB HDD, I returned it for a refund. Now I want to try a Western Digital USB HDD but I need to know exactly what drivers and commands can be used to successfully recognize and mount the WD drive. My USB thumb drives can all be successfully recognized with the sg and usb-storage modules (as shown in the commands above). Is this all I would need to mount a Western Digital USB HDD or is there some other module that needs to be loaded? As I mentioned, the Gentoo Live DVD was able to recognize the drive. How was this done? Internet searches only provide comments from Ubuntu or Fedora users stating that "I plugged it in and it worked," which are next to useless. I need to know what modules (drivers) and basic commands can get a Western Digital USB external HDD to successfully mount.

After rebooting to the command console, and before starting X, I needed to re-install the nvidia-driver module for the new kernel. Doing "emerge nvidia-drivers" gave me the following error (the entire build log is attached): Preparing nvidia module make -j9 HOSTCC=x86_64-pc-linux-gnu-gcc CROSS_COMPILE=x86_64-pc-linux-gnu- 'LDFLAGS=-m elf_x86_64' IGNORE_CC_MISMATCH=yes V=1 SYSSRC=/usr/src/linux SYSOUT=/lib/modules/3.3.0/build CC=x86_64-pc-linux-gnu-gcc clean module *** Unable to determine the target kernel version. *** make: *** [select_makefile] Error 1 emake failed ERROR: x11-drivers/nvidia-drivers-295.20-r1 failed (compile phase): Unable to emake HOSTCC=x86_64-pc-linux-gnu-gcc CROSS_COMPILE=x86_64-pc-linux-gnu- LDFLAGS=-m elf_x86_64 IGNORE_CC_MISMATCH=yes V=1 SYSSRC=/usr/src/linux SYSOUT=/lib/modules/3.3.0/build CC=x86_64-pc-linux-gnu-gcc clean module Call stack: ebuild.sh, line 85: Called src_compile environment, line 3711: Called linux-mod_src_compile environment, line 2668: Called die The specific snippet of code: eval "emake HOSTCC=\"$(tc-getBUILD_CC)\" The first part of the build log (see attached file) indicates that the kernel source was correctly found (at /usr/src/linux), but for some reason the make process fails.

Frank Peters </pre> Frank Peters 2012-02-16T00:06:58 http://comments.gmane.org/gmane.linux.gentoo.amd64/16296 <pre>Hello, On an ordinary keyboard, the extended function keys, F13 to F24, should be accessible as Shift + Fn, where Fn are the keys F1 to F12. Well, up until a few days ago, the Shift+Fn combination was working as it should. Then suddenly, Shift+Fn stopped working correctly. I noticed it when using the Midnight Commander (MC) file manager where I extensively use Shift+F5 and Shift+F6 to conveniently rename and copy files. MC is a terminal program but the problem also shows up in some X programs that use Shift+Fn combinations. Because I have no need to closely monitor changes on my system I can't actually pinpoint any new install that may be responsible. My first guess would be a new version of xorg-server-1.11.1 that was emerged on October 2. I need to know how I can debug this situation further. Using xev to record key presses gives the following output when using Shift+F1: KeyPress event, serial 40, synthetic NO, window 0xe00001, root 0x121, subw 0x0, time 6919279, (23,152), root:(463,411), state 0x0, keycode 50 (keysym 0xffe1, Shift_L), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyPress event, serial 40, synthetic NO, window 0xe00001, root 0x121, subw 0x0, time 6921351, (23,152), root:(463,411), state 0x1, keycode 67 (keysym 0xffffff, VoidSymbol), same_screen YES, XKeysymToKeycode returns keycode: 63 XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False The data for the F1 keypress is not correct. Compare this output with the expected output that is shown in this forum thread: http://forums.gentoo.org/viewtopic-t-524537-start-0.html It appears that the X server is at fault. Can anyone using xorg-server-1.11.1 very that the Shift+Fn keys are broken?

Now when I boot into the new one, it works up to the level I am expecting (still need some drivers), but the keyboard act wierd. When I press "m" it types "0", and some other keys don't send anything at all. This issue starts when I start my xdm (configured to start slim). With the text run level (console), there's no issues until I start and stop xdm. I am not sure if I modified something long time ago in the config, to use different keymaps, but this issue didn't exist on the older laptop. What files could have such a configuration, that I need to look into ?

Shortly afterwards I tried to start OpenOffice and it would not start. The error message: Inconsistency detected by ld.so: dl-deps.c: 622: _dl_map_object_deps: Assertion `nlist &gt; 1' failed! (The same problem is reported here: http://forums.gentoo.org/viewtopic-p-6744468.html) Apparently this is due to the glibc update. A quick fix (since I need OpenOffice) would be to simply downgrade back to glibc-2.12-r2, but emerge will not allow me to do it: * Sanity check to keep you from breaking your system: * Downgrading glibc is not supported and a sure way to destruction * ERROR: sys-libs/glibc-2.13-r2 failed (setup phase): * aborting to save your system I'm not going to break my system. How do I override this? Note: I am not using the compiled Gentoo version of OpenOffice. My installation is the binary version from the OO web site. Also, LibreOffice, which I installed (from binary) as a possible fix, gives the same error message.

It seems to a correct suspicion. What follows is a short C program that reproduces my particular problem, but there are likely many other situations where GCC could fail. The code may be a difficult for some people to follow but only the output is what actually matters. Simpler examples will certainly exist but I have not had the chance to develop them. The program is included here as both in-line text and as a file attachment (gcc_test.c). The problem is described below. ------------------------------------ #include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; int main(void) { int n; double x; unsigned long int arg; unsigned long int *px = (unsigned long int*)&amp;x; x=0.0; n=0; arg=0x4010000000000000; while(n&lt;5) { printf("%lx %g\n",arg, x); *px=arg; printf("%lx %g\n\n",arg, x); n++; arg=arg+0x0010000000000000; } exit(0); } ------------------------- What this code does is not very important (it uses pointers to enter hexadecimal values into a floating point variable within a short loop). The output is what matters. Compiling with "gcc -O2 -march=native -o gcc_test gcc_test.c" produces this output: Loop: 0 Val = 4010000000000000, X before = 0 Val = 4010000000000000, X after = 0 --&gt; X should be 4!!! Loop: 1 Val = 4020000000000000, X before = 0 Val = 4020000000000000, X after = 4 Loop: 2 Val = 4030000000000000, X before = 4 Val = 4030000000000000, X after = 8 The printf statements are included before and after the variable, x, is assigned a value. Notice how in the first iteration of the loop the x variable does *not* get assigned a value. The value of x during the first iteration should be 4. The problem can be fixed by compiling the program with "O1" optimization: gcc -O1 -march=native -o gcc_test gcc_test.c Using "O1" the output now becomes: Loop: 0 Val = 4010000000000000, X before = 0 Val = 4010000000000000, X after = 4 --&gt; Now it works!!! Loop: 1 Val = 4020000000000000, X before = 4 Val = 4020000000000000, X after = 8 Loop: 2 Val = 4030000000000000, X before = 8 Val = 4030000000000000, X after = 16 This is now the correct output. In the first iteration the X variable is assigned the proper value. For anyone who wants to try to duplicate these results, please feel free to do so. So I will have to conclude that GCC-4.5.2 has serious problems. This kind of erroneous behavior could appear anywhere.

In particular, it would do somewhat poorly on various floating point tests that are available on-line. Because I do mathematical work on my machine, I used to regularly evaluate my software using these tests. However, for the past several years Linux/GNU has gotten nearly perfect scores on these same tests and it seemed that glibc and/or gcc had finally gotten the math code right. As a result of this, I stopped my regular evaluations of the software. Just recently I decided to run these tests again. I expected to see the same nearly perfect scores but, to my surprise, a failure occurred in the area of complex number operations. This may not be a very serious failure, but it was not present during prior tests and thus it should not be present now. Possibly a fault has crept in somewhere either in glibc or gcc. Because I had stopped my regular testing I can't relate the failure to any specific version change of either package. I need to request a verification from any Gentoo users. All that needs to be done is run a straightforward software test. The software is called UCBTEST and is described at http://www.netlib.org/fp/ The source code, however, is ancient Unix (1995) code and must be patched. I have created a patched tarball that can run on recent Linux. This file is attached as ucbtest.tar.bz2 If one is accustomed to modern GUI software, this code is a mess, but it is rather straightforward to implement. Here are the steps: 1) Create a directory somewhere, e.g. /tmp/fp-test 2) Unpack the tarball into this directory. 3) Change into the /tmp/fp-test directory 4) Modify the ucbREADME/linux.sh file as follows: Line 10 -- specify a full path for the results directory -- all test results will be stored here -- e.g. /tmp/fp-test-results Line 11 -- specify the full path to the Unix time program -- ucbtest won't run without time -- for Gentoo just "emerge time" and the path will be "/usr/bin/time" Line 17 -- specify the full path to the test directory -- same as in step #1 Line 36 -- enter your CFLAGS here That's it as far as configuration. Now, from the top directory of the source just execute: ucbREADME/linux.sh The code will take several minutes to compile, execute, and complete. While the test is running it will spit out its progress to stdout. Upon completion a brief summary is given: UCBFAIL indicates problems! /tmp/fp-test-results/ccos_DP.output: ucbtest UCBFAIL in COS(X) at line 444 for generic /tmp/fp-test-results/clib_DP.output: ucbtest UCBFAIL in cabsd at line 701 for double /tmp/fp-test-results/clib_DP.output: ucbtest UCBFAIL in powd at line 701 for double /tmp/fp-test-results/clib_DP.output:UCBFAIL clib_DP.output , 25 out of 25 tests completed /tmp/fp-test-results/csin_DP.output: ucbtest UCBFAIL in SIN(X) at line 444 for generic only 11 out of 14 show UCBPASS! There are expected failures in the trigonometric tests since trigonometric performance is not specified in IEEE754/854. The failure in powd (double power function) is also expected. But everything else should have passed. In my case, the new failure occurs in the cabsd test, which is the absolute value for complex numbers. I have never seen this error previously and it may possibly indicate some problem with either glibc or gcc. The results directory is also a mess (someone should really clean this code up). In the results directory (see step #4) all detailed test results are contained in the *.output files. Anyway, if anyone wants to try this test, the steps have been outlined. In spite of the messiness, the procedure is really quite simple, and the ucbtest is a very good test of floating point performance.

If I run mplayer I get sound also. If I use firefox-bin with a java applet that plays sound, I get no sound at all. I can't load this applet in firefox, which is why I still use firefox-bin for it. Googling "no sound in firefox java" gives lots of hits, mainly from people with the same problem. 1 solution was to "modprobe snd-pcm-oss" which did not help. I.m fairly sure this is redundant with base layout 2. I upgraded the kernel twice, from linux-2.6.36-gentoo-r5 where I initially had the problem, to linux-2.6.36-gentoo-r8 and now on linux-2.6.38-gentoo-r6 paying careful attention to all the sound related configuration options. This had no effect. I've run out of things to try, so I'm asking the list. I previously had a problem where the first firefox session would get sound, but no subsequent application, including firefox would have sound, in other words the first invocation of firefox would lock the sound. I could live with that, this current problem is far more annoying. </pre> Daiajo Tibdixious 2011-06-17T23:25:40 http://comments.gmane.org/gmane.linux.gentoo.amd64/16171 <pre>On a system which serves a LAN as NAT gateway, when the ADSL (pppoe) link dies or when I restart net.ppp0, a lot of services like named, dhcpd, squid, samba, sshd, etc are also restarted, for which there is no reason.
