Having your distro and release version in your profile will get more specific answers.
Log in as root and give this command:
cat /proc/pci | less
I have an AGP card and this shows up for me:
Bus 1, device 0, function 0:
VGA compatible controller: nVidia Corporation NV11 (GeForce2 MX) (rev 161).
Master Capable. Latency=64. Min Gnt=5.Max Lat=1.
Non-prefetchable 32 bit memory at 0xce000000 [0xceffffff].
Prefetchable 32 bit memory at 0xc0000000 [0xc7ffffff].
Can you figure out your video card from this?
1. Can you find that computer distributor on the internet and look up the specifications?
2. Can you open the case and look?
Handy bash commands for finding out stuff in Linux:
# Find CPU specifications
# Find running kernel version
# What compiler version do I have installed
# What is the running kernel and compiler installed
# Find X server version
# What pci cards are installed and what irq/port is used
# Memory and swap information

# How are the hard drives partitioned
# How much free drive space
# Show disk usage by current directory and all subdirectories
du | less
# What takes up so much space on your box
# Run from the directory in question and the largest chunk shows up last
find $1 -type d | xargs du -sm | sort -g
# What is the distribution
# For finding or locating files
# Use dmesg to view the kernel ring buffer (error messages)
dmesg | less
# Watch error messages as they happen (sysklog needed)
as root, tail -f /var/log/messages
(shows last 10 lines, use a number in front of f
for more lines)
# What processes are running
# Find a process by name
ps -ef | grep -i <plain text>
For example, XCDroast
ps -ef xcdroast
# See current environment list, or pipe to file
env | more
env > environmentvariablelist.txt
# Show current userid and assigned groups
# See all command aliases for the current user
# See rpms installed on current system
rpmquery --all | more
rpmquery --all > <filename>
rpmquery --all | grep -i <plaintext>
# What directory am I using
# Get ls colors in less
ls --color=always | less -R
Look at man <command>
or info <command>
for the flags I used and for other options you can use for bash commands.
