Slackware 12.1 problems on Thinkpad T21
Right... so here's the story. A friend got pissed off at WinXP and asked me to setup linux on his Thinkpad T21.
I'd like to think I know my way around Slack decently, but this is the first laptop I've worked on with linux. I've got the following problems: --when logging out of any desktop and *trying* to get back to kdm, the screen goes black and the system goes unresponsive (only taking out the battery at this point does anything). --ethernet card(e100) isn't working. I've heard that it might be because of ACPI. I've been to Thinkwiki and Linux-laptop as well as a healthy ammout of googlin'. Nothing seems to be any specific help [not written 'for dummies'] http://www.thinkwiki.org/wiki/Category:T21 has general specs. Specifics: 20gb hdd, 128mb ram, 256mb swap, red nub mouse thingy. Any solutions, hunches, or gut-feelings will be greatly appreciated. |
First - instead of pulling out the battery try to push the main power button for appr. 5..7 seconds.
This should switch off your T21 as it happens to my T23 when there is a serious lack of response. Assuming that you have one of the latest Slack installed please check the content of /etc/modprobe.d/blacklist for this entry: blacklist eepro100 For my T23 it is a must so set yours the same way. It should be uncommented (without # at the beginning of the line). After rebooting your T21 invoke this at the terminal: lsmod | grep 100 And you should get something like this in return: e100 35724 0 which means that proper module for ethernet card is loaded. According to problem with leaving graphical managers like KDE/Xorg please post here your /etc/X11/xorg.conf content. I had a similar problem some time ago and a newer Savage video driver fixed it. Also disabling 3D rendering in xorg.conf may temporarily fix the problem. Commenting (#) these entries: #Load "dri" #Load "glx" should do the easy (but not elegant) trick. |
Hi WideEyedSleeper, There is a thread here that may help with the kdm problem. For the nic problem please post the following output.
Code:
/sbin/lspci -v Good luck. ;-) |
Brodo:
eepro100 is blacklisted, commented out 3d rendering as you suggested. Peacedog: I'm using the default huge.smp kernel, you know, cause it's the default I assume it's safe. as for the commands you suggested: lspci -v: Code:
00:00.0 Host bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 03) Code:
Module Size Used by Code:
eth0 Link encap:Ethernet HWaddr 00:03:47:20:1e:b5 Thanks for both your help so far in this. |
So your NIC is working, you just need to configure it with netconfig.
What about kdm, is it working yet? |
The e100 module is loaded, have you tried running
Code:
netconfig Good luck. ;-) |

As for your KDM troubles, did disabling DRI "fix" the issue? If not (or if you want to try to get DRI working), you should run `xorgconfig` and select one of the few Savage drivers listed there. There are a few Savage drivers you can try -- one listed near the beginning of the list (if I recall correctly) and some Savage S3 drivers way down the list (in the "S" section, oddly enough). Using a different driver may fix the problem. I've heard the DRI and Savage cards don't mix very well, so I can't predict how successful an attempt at enabling DRI would be. |
the logout issue is fixed.
I've been using slackware as a desktop for about 4 years now (mandrake for 2 years before that), this is my first time getting into linux on a laptop. The huge kernels have never been an issue before; I figure if it works, why mess with things. What is the advantage to using the generic-smp? My netconfing couldn't be simpler. Just put in the same thing I did post-installation, host/domain name, everything else is automatic from DHCP. I've read that the ethernet problem may be because of using acpi and that using apm would fix that. I sure don't know how to switch the two up. |
I upgraded from 12 to 12.1 (thinkpad t21) without problem but I don't remember if I use my own kernel.
The screen is blanking because the driver has problem with Default depth. Change it. (vi /etc/X11/xorg.conf) Also Code:
echo modprobe ibm_acpi >> /etc/rc.d/rc.modules Code:
/sbin/modrobe speedstep-smi I do: Code:
echo 550000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed my xorg.conf Code:
