1) After the latest batch of updates X crashed on startup. I read |
| 2 |
through the list, and followed someone's suggestion to re-emerge all |
| 3 |
drivers listed by the command... |
| 4 |
|
| 5 |
equery list | grep x11-drivers/ |
| 6 |
|
| 7 |
Thank you sir. That was easy, and I now have X operational again. |
| 8 |
|

2) I go through /var/log/portage/elog after updates, and check for |
| 10 |
warnings. I got the following with xinit-1.0.8-r4 |
| 11 |
> WARN: postinst |
| 12 |
> If you use startx to start X instead of a login manager like gdm/kdm, |
| 13 |
> you can set the XSESSION variable to anything in /etc/X11/Sessions/ or |
| 14 |
> any executable. When you run startx, it will run this as the login |
| 15 |
> session. |
| 16 |
> You can set this in a file in /etc/env.d/ for the entire system, |
| 17 |
> or set it per-user in ~/.bash_profile (or similar for other shells). |
| 18 |
> Here's an example of setting it for the whole system: |
| 19 |
> echo XSESSION="Gnome" > /etc/env.d/90xsession |
| 20 |
> env-update && source /etc/profile |
| 21 |
|
| 22 |
Could someone please explain in plain English what this means? I.e. |
| 23 |
what are the plus and minus sides of doing the above? Should I bother? |
| 24 |
|
| 25 |
3) I notice that gcc-4.3.2-r3 has been installed. I understand that |
| 26 |
the commands to upgrade are... |
| 27 |
|
| 28 |
gcc-config i686-pc-linux-gnu-4.3.2 |
| 29 |
env-update && source /etc/profile |
| 30 |
|
| 31 |
Have there been any problems encountered with 4.3.2? Do I need to |
| 32 |
re-emerge sytem and world? Actually, I might decide to clean up CFLAGS |
| 33 |
in my /etc/make.conf from the current... |
| 34 |
CFLAGS="-O2 -march=prescott -mmmx -msse -msse2 -msse3 -mfpmath=sse -fomit-frame-pointer -pipe" |
| 35 |
|
| 36 |
to a simpler... |
| 37 |
CFLAGS="-O2 -march=native -mtune=native -mfpmath=sse -fomit-frame-pointer -pipe" |
| 38 |
|
| 39 |
and rebuild with that. |
| 40 |

4) Speaking of /etc/make.conf, there was some news about Radeon HD |
| 42 |
cards being moved to a separate driver group and requiring a change in |
| 43 |
/etc/make.conf. I'm using a card from an older computer, which lspci |
| 44 |
shows as... |
| 45 |
|
| 46 |
ATI Technologies Inc RV280 [Radeon 9200 PRO] (rev 01) |
| 47 |
|
| 48 |
Since X is working, I assume that my card is not a member of the Radeon |
| 49 |
HD family. My /etc/make.conf includes the lines... |
| 50 |
|
| 51 |
INPUT_DEVICES="keyboard mouse" |
| 52 |
VIDEO_CARDS="intel vga" |
| 53 |
|
| 54 |
and things appear to be working. The "intel" is in case I ever switch |
| 55 |
back to the onboard built-in video chip. After ipv6 was snuck into the |
| 56 |
defaults, I started off my USE with "-*", so I still don't have dbus and |
| 57 |
hal. |
